◆----->Probability=favourable outcomes/total number of outcomes.

◆P(girl)=10/25

◆P(girl)=2/5

◆Probability of girls not win or boys win

●P(boys will win)=1-2/5

◆Taking L.C.M

Answer 2

Total favourable events=25
event of boys be winner =25-10=15
therefore,P(A)=15/25=3/5.
Therefore, the probability that the winner is boys is 3/5.
