Question

In Cary's basketball career, he's made 80% of his free throws, plus or minus 5%. If he attempts 200 free throws this season, what is the range of successful free throws he can expect to make?

Answer 1

150 to 170 successful free throws

Explanation:

Total % of free throws made = 80%±5%

If attempted number of free throws = 200

Range of successful free throws to expect :

(80% - 5%) of 200 TO (80% + 5%) of 200

75% of 200 TO 85% of 200

(0.75 * 200) TO (0.85 * 200)

150 TO 170

150 - 170 successful free throws
