Question

When a coin is tossed, what is the probability of occurrence of "head" as the outcome?

• A. $\frac{1}{4}$
• B. $\frac{3}{5}$
• C. $\frac{1}{3}$
• D. $\frac{1}{2}$

Answer 1

The correct option is D $\frac{1}{2}$

$Probability=\frac{Numberoffavorableoutcomes}{totalnumberofoutcomes}$
No. of favorable outcome = 1 (Head)
Total outcomes = 2 (Head or Tail)
Hence,
$Probability=\frac{1}{2}$
When you flip a coin, there are two outcomes either head or tail. So the probability of occurrence of the head is the same as the probability of occurrence of the tail that is $\frac{1}{2}$.
