If E and Fevents with `P(E) <= P(F)` and `P(E nn F)>0`, then (a) occurrence of E(b) occurrence of Foccurrence of Foccurrence of E(c) non-occurrence of Enon-occurrence of F(d) none of the above implications hold

If E and Fevents with P(E) 0, then (a) occurrence of E(b) occurrence of Foccurrence of Foccurrence of Ec(c) non-occurrence of Enon-occurrence of F(d) none of the above implications hold

If E and F are events with P(E) le P(F) and P(E nn F) gt 0, then

If P (E) denotes probability of occurrence of event E, then :

Suppose E and F are two events of a random experiment.If the probability of occurrence of E is (1)/(5) and the probability of occurence of F given E is (1)/(10), then the probability of non- occurrence of at least one of the events E and F is

The probability of an occurrence of event A is 0.7 and that of the occurrence of event B is 0.3 and the probability of occurrence of both is 0.4.

If A is an event and P(A) and P(vec A) denote the probabilities of occurrence and non occurrence respectively of event A, the P(A)+P(vec A)

If the probability of the occurrence of a certain event E is 3/11, find (i) the odds in favour of its occurrence, and (ii) the odds against its occurrence.

If the probability of occurrence of an event is p then the probability of non-happening of this event is

Let A and B be two independent events with P(A) = p and P(B) = q. If p and q are the roots of the equation ax^(2) + bx + c = 0 , then the probability of the occurrence of at least one of the two events is
