Mand N are two events P (M) = 0,60, P (N) = 0.20, and P (M and N) = 0.1.

Find the probability of P (Mor N).

0.7

Step-by-step explanation:

This can be easily solved if we know the formula:

P (A or B) = P (A) + P (B) - P (A and B)

So, for this problem, we can modify the formula to be:

P (M or N) = P (M) + P (N) - P (M and N)

Using given information, we can solve:

P (M or N) = P (M) + P (N) - P (M and N)

P (M or N) = 0.6 + 0.2 - 0.1

P (M or N) = 0.7

Last answer choice is right, 0.7
