General guidance

Concepts and reason
The problem deals with the concept of probability of independent events. The two events are said to be independent of each other when one event occurs then it does not affect the second event. For example: tossing a coin.

Fundamentals

The formula of the probability for the two independent two event is:

P(ANB)=P(A).P(B)

Here A&Bare two independent events.

Step-by-step

Step 1 of 2

The probability of occurring of event isP(A)=0.65.

The probability of intersection of the two events A&Bis P(ANB)=0.26

Therefore the probabilities are as P(A)=0.65 and P(ANB)=0.26.

Step 2 of 2

Since the probability for the two independent two event is as:

P(ANB)=P(A).P(B)

Then the probability of the event will be,

P(B)=P(ANB)
P(A)
0.26
0.65
= 0.4

Therefore, the probability of the event isP(B)=0.4.

Using the formula of the probability for the two independent two event the probability of the event is.

Answer

Therefore, the probability of the event isP(B)=0.4.
