Answer:
a) 0.85
b) 0.15
c) 0.40
d) 0.70
Step-by-step explanation:
P(A) = 0.55
P(B) = 0.45
P(A n B) = 0.15
a) Probability of A or B occurring = P(A u B) = P(A) + P(B) - P(A n B) = 0.55 + 0.45 - 0.15 = 0.85
b) Probability of A and B occurring = P(A n B) = 0.15
c) Probability of just A occurring = P(A n B') = P(A) - P(A n B) = 0.55 - 0.15 = 0.40
d) Probability of just A or just B occurring = P(A n B') + P(A' n B) = 0.4 + (0.45 - 0.15) = 0.4 + 0.3 = 0.70
