Question

you select a card at random from the cards that make up the word replacement. on each card, there is one letter. without replacing the card you choose a second card. find the prbabillity of choosing a consonant and then an E.

Answer 1

21/110

Explanation:

REPLACEMENT

11 letters

7 consonants

3 e's

P(consonant) = consonant/total = 7/11

Now we keep that card so there are only 10 cards left

P (e) = e / total = 3/ 10

P ( consonant then an e keeping the first card) = 7/11 * 3/10

=21/110
