Answer: 18%
Step-by-step explanation:
We know that if A and B are independent events,
then the probability that events A and B both happens is
P(A and B) = P(A) x P(B).
Let A be the event that it will rain on Wednesday
Then P(A)=30%=0.3
Let B be the event that it will rain on Saturday
then P(B)=60%=0.6
The probability that it will rain on Wednesday and on Saturday
P(A and B)=0.3 x 0.6=0.18=18%
