The probability of the simultaneous occurrence of two events A and B is p. If the probability that exactly one of A, B occurs is q, then which of the following alternatives is incorrect ?

A

`P(barA) + P(barB) = 2 + 2q - p`

B

`P(barA) + P(barE) = 2- 2 p - q`

C

`P(A cap B // A cup B) = (p)/(p +q)`

D

`P(barA cap barB) = 1 - p - q`
