Question

Suppose you select 2 letters at random from the word compute without replacement. Find each probability. P(2 vowels)

Answer 1

Answer:

1/7

Step-by-step explanation:

The word "compute" has 7 letters, 3 of which are vowels.

The probability that the first letter is a vowel is 3/7.

There's no replacement, so there are 6 letters left, 2 of which are vowels.

The probability that the second letter is a vowel is 2/6.

The probability of 2 vowels is therefore:

P = (3/7) (2/6)

P = 1/7
