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=>occurrence of F(b) occurrence of F=>occurrence of E(c) non-occurrence of E=>non-occurrence of F(d) none of the above implications hold

If E and F events with P(E) 0 , then (a) occurrence of E => occurrence of F(b) occurrence of F => occurrence of E (c) non-occurrence of E => non-occurrence of F(d) none of the above implications hold

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

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 occurrence of F given E is 1//10 . Then the probability of non-occurance of atleast one of the events E and F is

Three coins are tossed. Events E_1, E_2, E_3 and E_4 are defined as follows. E_1 : Occurrence of at least two heads. E_2 : Occurrence of at least two tails. E_3 Occurrence of at most one head. E_4 : Occurrence of two heads. Describe the sample space and events E_1,E_2,E_3 and E_4 . Find E_1uuE_4,E'_3 . Also check whether E_2 and E_3 are equal.
