Find the probability that it will not snow.
Answer to Problem 4STP
H
Explanation of Solution
Given:
A meteorologist says that the probability of snow today is 45%.
Formula Used :
P(E) + P(not E) = 1
Calculation:
P(snow) = 45% = 0.45
P(snow) + P(not snow) = 1
P(not snow) = 1-0.45 = 0.55
So, the correct option is H.
