Answer 1

Answer:

38.18%

Step-by-step explanation:

Experimental probability is probability that is determined on the basis of the results of repeated experiments.

Experimental Probability = The number of times a result happens / The number of times the experiment is carried out *100%

In this problem, The number of times a result happens is the number of times Pedro sees heads, which is 21. The number of time the experiment is carried out is 55.

So the result is 55/21 *100% = 38.181818... * 100%= 38.18%

Hope you learn with joy and high grades !
