Answer:
50%
Step-by-step explanation:
Given that :
Let Probability of rain today = P(rain today) = 50% = 0.5
The complement of an event A denoted as A' means the opposite of event A is obtained by subtracting event a from 1.
P(rain today) = 0.5
The complement of P(rain today) ; means the probability that it will NOT rain today;
Hence, P(raintoday') = 1 - 0.5 = 0.5 = 50%
