SOLUTION: Use the addition rule to determine the following probability: a. if P(E)=0.5 & P(F)=0.4 and E & F are mutually exclusive, find P(EnF) P(EnF) = P(E)+P(F)

SOLUTION: Use the addition rule to determine the following probability: a. if P(E)=0.5 & P(F)=0.4 and E & F are mutually exclusive, find P(EnF) P(EnF) = P(E)+P(F) - P(EnF) b.If P(E)=0

Question 1110170: Use the addition rule to determine the following probability:
a. if P(E)=0.5 & P(F)=0.4 and E & F are mutually exclusive, find P(EnF)
P(EnF) = P(E)+P(F) - P(EnF)
b.If P(E)=0.4 & P(F)=0.2 & E and F are mutually exclusive, find P(EnF)

I assume you are using P(EnF) to represent the probability that both E and F are true.

In that case, both your problems say that E and F are mutually exclusive. That means P(EnF) is 0. Any other information given in the problems is irrelevant.
