Calculate the following:

P (consonant, even number) =

Give your answer as a decimal.

(Hint: A consonant is any letter besides (a, e, I, o, u)

Answer 1

Answer: 0.375

=====================================================

Work Shown:

A = P(consonant)

A = 3/4 since there are 3 consonants out of 4 letters in the word "SKIP".

B = P(even number)

B = 3/6

B = 1/2

P(consonant, even number) = A*B

P(consonant, even number) = (3/4)*(1/2)

P(consonant, even number) = 3/8

P(consonant, even number) = 0.375
