Jacqueline flips two coins at a time, and conducts a number of trials to get the data:Two Heads 15One Head 17No Heads 10What is the experimental probability of getting two heads?

To calculate the experimental probability of getting two heads, you need to divide the number of successful outcomes (getting two heads) by the total number of outcomes (all trials).

Step 1: Identify the number of successful outcomes. In this case, Jacqueline got two heads 15 times.

Step 2: Identify the total number of outcomes. This is the total number of trials Jacqueline conducted. Add up the number of times she got two heads, one head, and no heads: 15 (two heads) + 17 (one head) + 10 (no heads) = 42 trials.

Step 3: Divide the number of successful outcomes by the total number of outcomes to get the experimental probability. So, the experimental probability of getting two heads is 15 (two heads) ÷ 42 (total trials) = 0.357, or 35.7% when expressed as a percentage.
