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
