Answer:

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)
