Question

The probability that a 'P and C' question will be asked in IIT JEE is

\frac{2}{5}

and probability question is uploaded is

\frac{4}{7}

. If the probability of getting at least 1 is

\frac{2}{3}

what is the probability that questions from both the topics are asked.

Options:

A . 17105

B . 16105

C . 135

D . 635

Answer: Option A
:
A
P(A U B)= P(A)+ P(B)- P(A intersection B)

\frac{2}{3} = (\frac{2}{5}) + (\frac{4}{7}) - x

x = \frac{17}{105}
