The events x and y are mutually exclusive. suppose p(x)=0.05 and p(y)=0.02. what is the probability of either x or y occurring? your answer is . what is the probability that neither x nor y will happen? your answer is . (if your answer is '0.4', for example, don't write it as '.4')

Probability of x occurring is p(x)=0.05
Probability of y occurring is p(y)=0.02
Given that the two events are mutually exclusive, the probability of the two events occurring will be given by:
P(x or y)=0.05+0.02=0.07
The answer is 0.07

The probability that neither x nor y occurs will be given by:
1-P(x or y)
=1-0.07
0.93

I'm just guessing, but my answer would c. 0 to 300.
