3. press the button to flip the coin 15 more times.
4. what is the experimental probability of flipping a head after twenty flips of the coin? 9/20
5. what is the theoretical probability of flipping a head? 9/11 9/20 1/2

Explanation:

Step1: Recall coin - flip probability concept

A fair coin has 2 equally likely outcomes (head or tail).

Step2: Calculate theoretical probability

The theoretical probability of getting a head in a single fair - coin flip is the number of favorable outcomes (1, which is getting a head) divided by the total number of possible outcomes (2, head or tail). So the probability $P=\frac{1}{2}$.

Answer:

$\frac{1}{2}$
