Question

A coin is tossed 20 times. The outcomes H (for heads) and T (for tails) are recorded:

H T H T T T T H H T T H H T T T H H H T



What is the experimental probability of getting heads (H)?



0.45


0.5


0.65


0.8

Answer 1

0.45

Explanation:

you count all of the heads and divide the number by 20

Answer 2

The correct answer option is 0.45.

Explanation:

Total number of times a coin is tossed = 20

Total number of times the outcome was a H = 9

Total number of times the outcome was a T = 11

To find the experimental probability of getting heads (H), we need to divide the total number of times the outcome was H by the total number of times the coin was tossed.

Experimental probability of getting heads (H) = 9 / 20 = 0.45
