{H,T}
If A and B are mutually exclusive events then p(A∪B)=
Suppose an outcome A occurs m times out of n equally likely outcomes in an experiment.Then odds in favour of A =
n/m
m/n
(n-m)/m
m/(n-m)
E and F are two events associated with a random experiment for which p(F)=0.35 ,p( E or F)=0.85 , p(Eand F)=0.15.Find p(E)
0.35
0.65
0.5
0.25
Two cards are drawn successively with replacement from a well-shuffled pack of 52 cards. The probability of drawing two aces is
1/13
1/13×1/17
1/52×1/51
1/13×1/13
If A and B are two events in a sample space then
p(A∪B)≥p(A)+p(B)
p(A∪B)≤p(A)+p(B)
p(A∪B)=p(A)+p(B)
