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 P(A//B)=(1)/(3), P(B)=(1)/(4) and P(A)=(1)/(2) , find the probability that exactly one of the events A and B occurs.

if P(A|B) = 1/3 , P(A) = 1/4 and P(B) = 1/2, find the probability that exactly one of the events A and B occurs.

If A and B are two events, the probability that exactly one of them occurs is given by a. P(A)+P(B)-2P(AnnB) b. P(Ann B )+P( AnnB') c. P(AuuB)-P(AnnB) d. P( A' )+P( B' )-2P( A' nn B' )

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 -

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 -

If A and B are two events, then probability that exactly one of them occurs is -

If Ma n dN are any two events , the probability that exactly one of them occur is a) P(M)+P(N)-2P(MnnN) b) P(M)+P(N)-P(MnnN) c) P(M^c)+P(N^c)-2P(M^cnnN^c) d) P(MnnN^c)+P(M^cnnN)

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?

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
