A coin is tossed twice. The probability of getting head both the times is
$\frac{1}{2}$
$\frac{1}{4}$
$\frac{3}{4}$
$1$
Consider the set of all $7-$digit numbers formed by the digits $0,1,2,3,4,5,6$, each chosen exactly once. If a number is randomly drawn from this set, the probability that it is divisible by $4$ is
Three coins are tossed together, then the probability of getting at least one head is
One card is drawn from a well shuffled deck of $52$ cards. If each outcome is equally likely, calculate the probability that the card will be a black card (i.e., a club or, a spade)
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 $A^{\prime }.$
Consider the experiment in which a coin is tossed repeatedly until a head comes up. Describe the sample space.
