Question

Out of 25 students participating in a debate, 8 are girls. Find the probability that the winner is a boy,​
please help me

Answer 1

Answer:

• Total Number of Boys = 25
• No. of Girls = 8

Therefore,

• Number of winner (boys) = 25-8 = 17

Now, we have to calculate the probability of winner

• P(E) = No. of winner(boy) / Total number of students

Substitute the value , we get

→ P(E) = 17/25

Hence, the required probability is 17/25 .

Answer 2

Answer:

$\frac{17}{25}$

Step-by-step explanation:

Given,

Total no. of outcomes = 25

No. of girls = 8

So, no of boys = 25 - 8

= 17

Therefore, Probability of getting the winner as a boy is

$= \frac{no. \: of \: favourable \: outcomes}{total \: no. \: of \: outcomes}$

$= \frac{17}{25} (ans)$
