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

Please respond to the question above.

7/10 + (0.6)(0.3)= ?

or
6/10 + (0.7)(0.4)= ?
Two ways of doing it that yield the same answer

3/25

To find the probability that it will be rainy or windy on Monday, we need to find the probability of each event separately and then add them together.

The probability of it being rainy is 7/10, and the probability of it being windy is 6/10. Since the events are independent, we can multiply these probabilities:

P(Rainy and Windy) = P(Rainy) * P(Windy)
= (7/10) * (6/10)
= 42/100
= 21/50

So, the probability of it being rainy or windy on Monday is 21/50.

Therefore, the correct answer is option a. 21/50.
