Question

Events A and B are mutually exclusive. Find the missing probability.

P(A) = 3/10 P(B) = ? P(A or B) = 4/5

1/2

2/3

1/5

3/10

Answer 1

Answer:

1/2

Step-by-step explanation:

As they are mutually exclusive P(A and B) = 0 therefore the probability of P(A or B)= P(A) + P(B). Just do 4/5-3/10= 5/10=1/2
