Question

A balloon vendor has a 4 red 5 blue and 7 green balloon.He want to choose one of them at random to give to pooja. what is the probability of event that pooja gets


​

Answer 1

answer》4/9

solution 》

given:

no of red balloons:2

no of blue balloons:3

no of green balloons:4

let S be the sample space

▪︎n(S)=

no of red balloons+no of blue balloons+no of green balloons

=2+3+4=9

let C be the even of getting a green baloon

given:n(C)=4

▪︎p(C)=n(C)÷n(S)

=4/9

hence the probability of events that pranali gets a green baloons is 4/9
