Question

In the famous bollywood movie Sholay, Jai uses a coin in which both the faces are same i.e. heads. Jai always uses this coin to settle disputes with his friend named Viru by tossing it. In the case of a toss, Jai always calls heads. What is the probability that Jai will win the toss?

• A. $\frac{1}{4}$
• B. $\frac{1}{2}$
• C. $1$
• D. $\frac{1}{3}$

Answer 1

The correct option is C

$1$

The event here is tossing of a coin. As both the sides of the coin are same,
Number of possible outcomes = 1 (heads)
Number of favourable outcomes = 1 (as jai calls heads)
Probability of Jai’s win, P(E) = $\frac{numberoffavourableoutcomes}{totalnumberofoutcomes}$ = 1
Thus, this is a certain event as there is no way Jai is going to lose. The probability of a certain event is 1.
