Question

4. If P (E) = 0.72, then P (not E) is _______.​

Answer 1

QUESTION :

In an experiment, E and F are the only two possible outcomes. If P(E) = 0.72, then find P(F).

Step-by-step explanation:

ANSWER :

The probability of F is P(F) = 0.28

Given : In an experiment, E and F are the only two possible outcomes. If P(E) = 0.72.

To find : The value of P(F) ?

Solution :

We know that maximum probability for occurrence of any event is 1.

So, P(E) + P(F) = 1

We have given, P(E) = 0.72

Substitute the value,

0.72 +P(F) = 1

P(F) = 1 - 0.72

P(F) = 0.28
