True or False:
If A = {0, {0}} and b = {0}, then B `in` A and also B`sub`A

If a<0 and b<0, then he point P(a,b) lies on

True or false If A and B are independent events then A' and B' are also independent.

State True/False P(A) = 0.6, P(B) = 07 and P(A/B) = 0.3, then P(A nn B) is 0.21

True or false If A and B are independent then P(exacttly one of A and B occurs)=P(A)P(B')+P(A')P(B).

If P(A) = 0·4, P(B) = 0.2 and P(B/A) = 0·5, then P(A nn B) is :

Say True or False giving reason : P(A) = 0.3, P (B) = 0.45, P (A and B) = 0.2 . A and B are mutually exclusive events.

Say True or False giving reason : P (A) = 0.35, P (B) = 0.65 , A and B are complementary events.

Incase of each of the following statements, state whether it is true or false : If vec a and vec b are the adjacent sides of a parallelogram, then vec a* vec b =0

If P(A)=0.6, P(B)=0.7 and P(AuuB)=0.9 , then find P(A/B) and P(B/A)
