Sample space = {A, B, C, D} P(A) = 0.2, P(B) = 0.1, P(C) = 0.3, P(D) = 0.4 P(A, C) =

Question

a. 0.3

b. 0.4

c. 0.5

d. 0.6

Answer 1

 

Probabilities are

P(A) = 0.2

P(C) = 0.3

Then P(A,C),

We know that  P(A,C) = P(A) + P(C)

 P(A,C) = 0.2 + 0.3

 P(A,C) = 0.5

Therefore  P(A,C) is 0.5

Option (c) is the correct answer.
