suppose you roll two number cubes and pick a letter from the alphabet at random. find the probability that you roll 2 even numbers and pick one of the vowels a,e,i,o or u
1: 1 2 3 4 5 6 2: 1 2 3 4 5 6 3: 1 2 3 4 5 6 4: 1 2 3 4 5 6 5: 1 2 3 4 5 6 6: 1 2 3 4 5 6 36 possible number combinations 9 are even-even so 25% for the dice and for 5/26 letters .25 x probability of 5/26 so for one letter 1/26 = x/100 so 5/26 = x/100 x = 19.23% so .25 x .1 or about 4.81 percent
