## Answer

## 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:

Here are two independent events.

## Step-by-step

### Step 1 of 2

The probability of occurring of event is.

The probability of intersection of the two events is

Therefore the probabilities are as and .

### Step 2 of 2

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

Then the probability of the event will be,

Therefore, the probability of the event is.

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 is.

### Answer only

Therefore, the probability of the event is.

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

A&B

P(A)=0.65

A&B

P(ANB)=0.26

P(A)=0.65

P(ANB)=0.26

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

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

P(B)=0.4
