The probability of obtaining an even prime number on each die, when a pair of dice is rolled is
$\frac{1}{36}$
$\frac{1}{3}$
$\frac{1}{12}$
$0$
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 $^{\prime}$ not $A\,^{\prime}$.
If a coin be tossed $n$ times then probability that the head comes odd times is
Two cards are drawn one by one at random from a pack of $52$ cards. The probability that both of them are king, is
A bag contains $3$ red and $7$ black balls, two balls are taken out at random, without replacement. If the first ball taken out is red, then what is the probability that the second taken out ball is also red
