​

Answer 1

Answer:

the probability of boys is 25/10. and. 10/25 of girls

Answer 2

Answer:

5/7

Step-by-step explanation:

given:-

Total students = 35

Number of girls = 10

Number of boys = 35-10 = 25

Let A be the event of winning the debate by boys.

n(A) = 25 = number of events

Sample Space(S) = {1,2,......,35}

n(s) = 35 = Total Sample Space

Probability of boys winning a debate = n(A)/n(S) = 25/35 =5/7
