Question

The probability that a student will pass his examination is 0.73, the probability of the student getting a compartment is 0.13, and the probability that the student will either pass or get compartment is 0.96.

Options

  • True

  • False

MCQ
True or False

Solution

This statement is False.

Explanation:

Let E be the event that the student will pass

And F be the event that he will get compartment

∴ P(E) = 0.73, P(F) = 0.13 and P(E ∪ F) = 0.96

∴ P(E ∪ F) = P(E) + P(F) – P(E ∩ F)

= 0.73 + 0.13 – 0   ......[∵ P(E ∩ F) = 0]

= 0.86

But P(E ∪ F) = 0.96
