The probabilities of three mutually exclusive events are 2/3, 1/4, and 1/6. Is this statement correct?

Give the definition of mutually exclusive events.

Define with examples : Mutually exclusive events.

If A and B are two mutually exclusive events, then-

If (1+3p)/3,(1-p)/1,(1-2p)/2 are the probabilities of 3 mutually exclusive events then find the set of all values of p.

Statement-I : If (1)/(5)(1+5p), (1)/(3)(1+2p), (1)/(3)(1-p) and (1)/(5)(1-3p) are probabilities of four mutually exclusive events, then p can take infinite number of values. Statement-II : If A, B, C and D are four mutually exclusive events, then P(A), P(B), P(C ), P(D) ge 0 and P(A) +P(B)+P(C )+P(D ) le 1.

If the events A and B are mutually exclusive then-

If A and B are two mutually exclusive event then P(A-B) =

For two mutually exclusive events A and B, P(A) + P(B) equals to 1. The above statement is

For two mutually exclusive events A and B,P(A)=1/2and P(AcupB)=2/3 ,then the value of P(B) will be

The probability of hitting a target by three marksmen are 1/2, 1/3 and 1/4. Then find the probability that no one will hit the target when they fire simultaneously.
