Question

The number of elements in the sample space for the indicated experiment, where a coin is tossed four times is:

• A. $16$
• B. $8$
• C. $4$
• D. $32$

Answer 1

The correct option is A $16$

Since either coin can turn up Head $\left(H\right)$ or Tail $\left(T\right)$, when $1$ coin is tossed once, then total elements in sample space $=2$
When coin is tossed 4 times. So the total elements in sample space $=2^4=16$
