Question

You flip a coin and get tails $35$ out of $70$ times. What is the experimental probability of flipping tails the next time around?

• A. $25\%$
• B. $50\%$
• C. $75\%$
• D. $35\%$

Answer 1

The correct option is B $50\%$

Given:
$\bullet$ A coin is flipped $70$ times.
$\bullet$ Tail is obtained $35$ times.

The experimental probability $\text{P(T)}$ of flipping tails is given as:

Number of favorable outcomes $=$ Number of times Tail is obtained $=35$

Total number of outcomes $=$ Number of times the coin is flipped $=70$


$\text{P(T)}=\frac{\text{Number of times Tail is obtained}}{\text{Number of times the coin is flipped}}$

$\text{P(T)}=\frac{35}{70}$

$\text{P(T)}=\frac{1}{2}$

As we know that $\frac{1}{2}$ is equal to $50\%$, the experimental probability of flipping tails the next time around is $50\%$.

Therefore, option (b.) is the correct answer.
