Calculate P(A1 I B2) given the following table.

A1 A2

B1 0.4 0.2

B2 0.1 0.3

Homework Answers

Answer #1

SOLUTION:

From given data,

A1 A2
B1 0.4 0.2
B2 0.1 0.3

We know the formula for

P(A1 I B2) = P (A1 and B2) / P( B2)

Where,

P (A1 and B2) = 0.1

P( B2) = 0.1+0.3 = 0.4

By substituting the all values then we get,

P(A1 I B2) = P (A1 and B2) / P( B2)

P(A1 I B2) = 0.1 / 0.4

P(A1 I B2) = 0.25

The value for P(A1 I B2) = 0.25
