For the two events $A$ and $B$, $P(A) = 0.38,\,$ $P(B) = 0.41,$ then the value of $P(A$ not) is
$0.41$
$0.62$
$0.59$
$0.21$
(b) $P(\bar A) = 1 – 0.38 = 0.62.$
The probability of getting a total of $5$ or $6$ in a single throw of $2$ dice is
In a class of $60$ students, $40$ opted for $NCC,\,30$ opted for $NSS$ and $20$ opted for both $NCC$ and $NSS.$ If one of these students is selected at random, then the probability that the student selected has opted neither for $NCC$ nor for $NSS$ is
An unbiased die is tossed until a number greater than $4$ appears. The probability that an even number of tosses is needed is
Three coins are tossed once. Find the probability of getting exactly $2$ tails.
Consider the experiment of rolling a die. Let $A$ be the event 'getting a prime number ', $B$ be the event 'getting an odd number '. Write the sets representing the events $A$ but not $B$
