Question

A coin was tossed 10 times, out of which heads appeared 7 times. Based on the given data, what is the experimental probability of getting heads in the next toss?

• A. $\frac{6}{10}$
• B. $\frac{5}{10}$
• C. $\frac{7}{10}$
• D. $\frac{3}{10}$

Answer 1

The correct option is C

$\frac{7}{10}$

Number of times the coin was tossed = 10
So, the number of possible outcomes = 10.
Now, Number of heads = 7
As the favourable outcome is getting heads,
So, the number of favourable outcomes = number of heads = 7

Therefore, experimental probability of getting heads

= $\frac{\text{Number of favourable outcomes}}{\text{Number of all possible outcomes}}=\frac{7}{10}$
