(b) less than $0$
(c) greater than $1$
(d) anything but a whole number

Q. Let

A, B

and

C

be three events such that the probability that exactly one of

A

and

B

occurs is

(1 - k),

the probability that exactly one of

B

and

C

occurs is

(1 - 2 k),

the probability that exactly one of

C

and

A

occurs is

(1 - k)

and the probability of all

A, B

and

C

occur simultaneously is

k^{2},

where

0 < k < 1.

Then the probability that at least one of

A, B

and

C

occur is

A

and

B

are independent events. The probability that both

A

and

B

occur is

\frac{1}{20}

and the probability that neither of them occurs is

\frac{3}{5}

. The probability of occurence of

A

Q. Two events A and B are occuring simultaneously. Probability of occuring of event A is

0.4

and probability of events A and B occuring together is

0.8

. What will be the probability of non - occurance of B event if replacement is allowed?

Q. The probability of the event A occuring is 0.5 and of B occuring is 0.3.If A and B are mutually exclusive events then the probability of neither A nor B occuring is
