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.

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, given

P (A ∩ B) = 0.4

Thus, the given statement is False.

P ( A) = 0.7

P ( B) = 0.3

P ( both) = 0.4

P (A ∩ B) = P (A) x P (B)

P (A ∩ B) = 0.7 x 0.3

               = 0.21

P (A ∩ B) = 0.4

therefor the given statement is false
