Answer: Third Option

$P (M\ or\ N) = 0.8$

Step-by-step explanation:

In this case, we have two non-disjoint events.

So the probability of M or N occurring is

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

We know that in this problem

$P(M) = 0.7\\\\P(N) = 0.5$

$P(M\ and\ N) = 0.4$

$P (M\ or\ N) = 0.7 + 0.5 - 0.4$

$P (M\ or\ N) = 0.8$

The answer is the third option
