M and N are independent events. P(M | N) = 0.71. Find P(M)
mash [69]

Since M and N are independent events, P(M)=P(M|N)=0.71

Step-by-step explanation:

Two events A and B are said to be independent when the probability of A happening does not depend on whether B has happened or not.

In other word, this condition can be rewrite as follows:

P(A|B)=P(A)

where

P(A|B) is the probability of A happening  given that B has happened

P(A) is the probability of A happening

In this problem, we have:

- M and N are independent events: so M does not depend on whether N occurs or not

Therefore,

P(M)=P(M|N)

- Also, we know that

P(M|N)=0.71

Therefore, it follows that

P(M)=0.71
