A coin is tossed $3$ times by $2$ persons. What is the probability that both get equal number of heads
$\frac{3}{8}$
$\frac{1}{9}$
$\frac{5}{{16}}$
None of these
Three coins are tossed once. Find the probability of getting $3$ 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 $A$ and $B$
‘$X$’ speaks truth in $60\%$ and ‘$Y$’ in $50\%$ of the cases. The probability that they contradict each other narrating the same incident is
Two dice are thrown. The events $A, B$ and $C$ are as follows:
$A:$ getting an even number on the first die.
$B:$ getting an odd number on the first die.
$C:$ getting the sum of the numbers on the dice $\leq 5$
Describe the events $A^{\prime }.$
The probability of obtaining an even prime number on each die, when a pair of dice is rolled is
