Question

The theoretical probability of tossing two heads when tossing a pair of coins is 0.25. When the pair of coins was tossed 20 times, two heads came up only 2 times. Which procedure would result in an experimental probability that is closer to the theoretical probability?

toss the coins more than 20 times
toss the coins fewer than 20 times
count only those tosses that result in two heads or two tails
toss three coins instead of two coins

Answer 1

Toss the coins more than 20 times.

Explanation:

Toss the coins more than 20 times. The experimental probability gets closer to the theoretical probability when the sample size is larger.
