The Twelve Portals, Vol. Jongsma Jr. Therefore, the number of ways in which the 3 letters can be arranged, taken all a time, is 3! The different ways in which the 3 letters, taken 2 at a time, can be arranged is 3! When a letter occurs more than once in a word, we divide the factorial of the number of all letters in the word by the number of occurrences of each letter.
Solution :. In order to find the number of permutations that can be formed where the two vowels U and E come together. In these cases, we group the letters that should come together and consider that group as one letter. After 3 vowels take 3 places, no. It does not matter whether we select A after B or B after A. The order of selection is not important in combinations. To find the number of combinations possible from a given group of items n, taken r at a time, the formula, denoted by n C r is.
For example, verifying the above example, the different selections possible from the alphabets A, B, C, taken two at a time are. Problem 1: In how many ways can a committee of 1 man and 3 women can be formed from a group of 3 men and 4 women? Problem 2: Among a set of 5 black balls and 3 red balls, how many selections of 5 balls can be made such that at least 3 of them are black balls.
Selecting at least 3 black balls from a set of 5 black balls in a total selection of 5 balls can be. Therefore, our solution expression looks like this.
Problem 3: How many 4 digit numbers that are divisible by 10 can be formed from the numbers 3, 5, 7, 8, 9, 0 such that no number repeats? After 0 is placed in the units place, the tens place can be filled with any of the other 5 digits.
After filling the tens place, we are left with 4 digits. Problem 1: Click here. Step 2 : Compute the probability of selecting bag y and the probability of drawing a red ball from bag y. The product of these two values is the probability of selecting a red ball from bag y. Step 3 : The sum of the values arrived at step 2 and 3 is the answer to the question. When two numbers from this set are selected and multiplied, what is the probability that the product is less than zero?
Step 1 : Compute the different possibilities for x and y given that we have a set of distinct integers. Both x and y could be positive 5 positive and 1 negative ; both x and y could be negative 3 positive and 3 negative ; one of x or y is positive and the other is negative 4 positive and 1 negative.
Step 2 : From statement 1, we can deduce that neither x nor y is 0. All 3 possibilities listed above are possible. Therefore, we will not be able compute a unique value. Step 3 : Determine how many of the 3 possibilities will be valid if statement 2 is true. If we get only one possibility out of the 3, we will have a unique answer.
In that scenario, statement 2 will be sufficient. Else, combine the statements and evaluate whether we are able to narrow the possibilities down to one of the three. There are 4 identical pens and 7 identical books. In how many ways can a person select at least one object from this set? Concept : Selecting from a set of identical objects Step 1 : Compute the number of ways of selecting none or up to 4 pens from the set of 4 idential pens. Step 2 : Compute the number of ways of selecting none or up to 7 books from a set of 7 identical books.
Step 3 : The product of the result of steps 2 and 3 will give the number of ways of selecting none or all of the objects Step 4 : Subtract the only possibility of selecting none of the objects from the result of step 3 to arrive at the answer to this question.
How many odd 4-digit positive integers that are multiples of 5 can be formed without using the digit 3? Conditions : Odd multiple of 5; 4-digit positive integer; does not contain the digit 3 Step 1 : Compute the number of possibilities for the unit digit if the number is an odd multiple of 5 Step 2 : Compute the number of possibilities for the thousands place if it cannot be 3.
Step 3 : Compute the number of possibliities for the hundreds and tens place if those digits cannot include 3. Step 4 : The product of the results of steps 1 to 3 is the answer to the question. How many six-digit positive integers comprising only the digits 1 or 2 can be formed such that the number is divisible by 3? Condition : 6-digit positive integers; only digits to be used 1 or 2; divisible by 3 Step 1 : List down possibilities of the form of 6-digit numbers comprising only 1 or 2 that are divisible by 3.
Example Step 2 : Count the number of integers for each such possibility after factoring in the reorderings as applicable. Step 3 : Sum of the counts in step 2 is the answer to the question. How many five-digit positive integers comprising only the digits 1, 2, 3, and 4, each appearing at least once, exist such that the number is divisible by 4?
