Question

In tennis, Gabby serves an ace, a ball that can't be returned, 4 out of the 10 times she serves. What is the experimental probability that Gabby will serve an ace in the first match of the next game? Make a prediction about how many aces Gabby will have for the next 40 serves. Justify your reasoning.

Answer 1

Answer: 1/2

Explanation:

4 out of 10= {4/10}

4+4= 8~ {8/10}

8+4= 16~ {16/30}

16+4= 20~ {20/40}

20/40= (1/2) ←answer

Answer 2

The mathematical reasoning for this would be thus: (4/10) * 40 = 16 aces for her next 40 serves. Best of wishes! :)
