(2) what is the probability of winning a lunch box ?​

Answer 1

(1) The probability of winning a pen = $\frac{29}{70}$ = 41.42%

(2) The probability of winning a lunch box = $\frac{7}{70}=\frac{1}{10}$ = 10%

Step-by-step explanation:

A box contains slips having number from 30 to 99 written on it.

Total number of slips from 30 to 99 = 70 slips

Prize of pen for digit greater than 70 on slip.

Total number of slips greater than 70 = (99 - 70) = 29 slips

Jaya picks a slip out of the box.

(1) The probability of winning a pen = $\frac{29}{70}$ = 41.42%

Prize of winning a lunch box for having a slip with multiple of 10.

Total number of slips with multiple of 10 = 30, 40, 50, 60, 70, 80, 90 = 7 slips

(2) The probability of winning a lunch box = $\frac{7}{70}=\frac{1}{10}$ = 10%

(1) The probability of winning a pen = $\frac{29}{70}$ = 41.42%

(2) The probability of winning a lunch box = $\frac{7}{70}=\frac{1}{10}$ = 10%
