For the three events `A ,B ,a n dC ,P` (exactly one of the events `AorB` occurs)`=P` (exactly one of the two evens `BorC` )`=P` (exactly one of the events `CorA` occurs)`=pa n dP` (all the three events occur simultaneously)`=p^2w h e r eo

For the three events A, B and C, P(exactly one of the events A or B occurs) = P(exactly one of the events B or C occurs) =P(exactly one of the events C or A occurs)= p and P(all the three events occur simultaneously) = p^2, where 0ltplt1/2. Then, find the probability of occurrence of at least one of the events A, B and C.

For three events A, B and C, P (Exactly one of A or B occurs) = P (Exactly one of B or C occurs) = P (Exactly one of C or A occurs) = (1)/(4) and P(All the three events occurs simultaneously = (1)/(16) . Then the probability that at least one of the events occurs, is :

For three events A,B and C,P (Exactly one of A or B occurs) =P (Exactly one of B or C occurs) =P( Exactly one of C or A occurs) occurs) P (All the three events occur simultaneously) =(1)/(6). Then the probability that at least one of the events occurs,is : (7)/(64) (2) (3)/(16) (3) (7)/(32) (4) (7)/(16)

If A and B are two events,the probability that at most one of these events occurs is

If P(A) and P(B) are the probabilities of occurrence of two events A and B, then the probability that exactly one of the two events occur, is
