The probability that it will be rainy on Monday is 7/10. The probability that it will be windy on Monday is 6/10. These events are independent. What is the probability that it will be rainy or windy on Monday?:
a. 21/50
b. 29/50
c. 22/25
d. 3/25

Prob(A U B) = Prob(A) + Prob(B)  Prob(A ∩ B)
I got .88 or 22/25
