Question

The Letters: U E A R Q H C H L A

A set of cards with a letter on each card as shown above are placed into a bag. Howard picks a card at random from the bag. Determine the probability that the card is:

1. not a vowel

2. a letter P

3. not a letter P

Answer 1

Below in bold.

Explanation:

U E A R Q H C H L A

1. There are 10 letters of which 4 are vowels and 6 are consonants.

So Prob(Not picking a vowel) = 6/10 = 3/5.

2. Prob(P is picked) = Zero (as there is no P in the list)

3. Prob(Not a P) = 1. (as all letters are not ).
