State whether the statements are True or False.

The probability of an occurrence of event A is .7 and that of the occurrence of event B is .3 and the probability of occurrence of both is .4.

Answers (7)

Given data:

P (occurrence of event A) = 0.7

P (occurrence of event B) = 0.3

P (occurrence of both) = 0.4

Now,      

P (A ∩ B) = P (A) x P (B)

P (A ∩ B) = 0.7 x 0.3

               = 0.21

But, we know that

P (A ∩ B) = 0.4

Thus, the given statement is False.
 

False
