Question

Consider the following.
P(A) = 0.27 and P(B) = 0.36,
A and B are mutually exclusive events

(a) Find the probability P(A). (Give your answer correct to two decimal places.)


(b) Find the probability P(B). (Give your answer correct to two decimal places.)


(c) Find the probability P(A or B). (Give your answer correct to two decimal places.)


(d) Find the probability P(A and B). (Give your answer correct to two decimal places.)

Answer 1

A. I put 0.27
b. 0.36
c. 0.56 because I multiplied them both together.
d. I put 0.56 also but that was wrong?????
I got the whole thing wrong

Answer 2

Hints:
P(A∪B)=P(A)+P(B)-P(A∩B)
If A and B are mutually exclusive (ME), then P(A∩B)=0.
This should take care of (d)
