Please help fast

Answer 1

7/20

Explanation:

You have a total of 80 roles. section 1 is 28. 28/80 or 7/20.

Hope this help :)

Answer 2

The experimental probability is

(number of times it stopped over Sect. 2) / (total number of times you tried it)

Number of times it stopped in Section-2: 36

Total number of times you tried it: (20 + 36 + 24) = 80

Experimental probability of Section-2 = 36/80 = 9/20 = 45%
