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
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.)

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)
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)
