The probability of occurance of at least one of two events A and B is 0.6 while that of occurrence of both of them is 0.2. find the value of `P(A^c) + P(B^c)`

The probability of occurrence of at least one event of two events X and Y is 0.6.-If the probability of occurrence both is 0.2, find P(barX) + P(barY)

The probability that at least one of A and B occurs is 0.6. If A and B occur simultaneously with probability 0.3, then find the value of P(A^(prime))+P(B^(prime)) .

The probability that at least one of the events A and B occurs is (3)/(5) . If A and B occur simultaneously with probability (1)/(5) , then the value of P(A')+P(B') is -

The probability that at least one of the events Aa n dB occurs is 0.6. If Aa n dB occur simultaneously with probability 0.2, then find P( barA )+P( bar B )dot

If the probability that exactly one of the two events A and B occurs is p and the probability that both A and B occur is q, then -

Show that the probability that exactly one of the events A and B occurs is P(A) + P(B) - 2P(AB).

Show that the probability that exaclty one of the events A and B occurs is P(A) + P(B) - 2P(AB).

If two events A and B are such as P(A^(c ))=0.3, P(B)=0.4 and P(A cap B^(c ))=0.5 , find the value of P[B//(A cup B^(c ))] .

Let E and F be two independent events. The probability that exactly one of them occurs is 11/25 and the probability if none of them occurring is 2/25 . If P(T) denotes the probability of occurrence of the event T , then (a) P(E)=4/5,P(F)=3/5 (b) P(E)=1/5,P(F)=2/5 (c) P(E)=2/5,P(F)=1/5 (d) P(E)=3/5,P(F)=4/5

If P(A) = 2/7, P(B) = 6/11, what is the probability that at least one of the two independent events A and B will occur?
