Question

Suppose you roll two number cubes and pick a letter of the alphabet at random. Find the probability you roll 2 even numbers and pick one of the vowels a, e, i, o, or u.

Answer 1

step 1: there is 1/2 chance that you roll an even number
step 2: there is 1/2 chance that you roll an even number
step 3: there are 5 vowels(a, e, i, o, u) out of 26 alphabet letters, so there is 5/26 chance you pick a vowels

1/2*1/2*5/26 = 5/104 chance that this entire procedure occurs

Answer 2

thank you
