The probability of obtaining an even prime number on each die, when a pair of dice is rolled is
$\frac{1}{36}$
$\frac{1}{3}$
$\frac{1}{12}$
$0$
The probability of $A, B, C$ solving a problem are $\frac{1}{3},\,\frac{2}{7},\,\frac{3}{8}$ respectively. If all the three try to solve the problem simultaneously, the probability that exactly one of them will solve it, is
The probability of happening of an impossible event i.e. $P\,(\phi )$ is
Three coins are tossed once. Find the probability of getting $3 $ heads
On her vacations Veena visits four cities $( A ,\, B ,\, C$ and $D )$ in a random order. What is the probability that she visits $A$ just before $B$ ?
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 $A$ or $B$.
