Question

Hat is he probability of pick 1 green marble from a bag with 7 green and 8 blue marbles

Answer 1

7/15

Explanation:

No. of green marbles in the bag= 7

No. of blue marbles in the bag= 8

Total no. of marbles in the bag= 7+8=15

As we know that,

Probability( of a random event A)=
`(Favourable\ no.\ of\ elementary\ events)/(Total\ no.\ of\ elementary\ events)`

Hence in this case,

Favourable np. of elementary events (green marbles)=7

Total no. of elementary events (Total no. of marbles in the bag)= 15

Hence, Probability of picking a green marble from the bag=
`(7)/(15)`
