Answer:
7/15
Step-by-step explanation:
<em>No. of green marbles in the bag= 7</em>
<em>No. of blue marbles in the bag= 8</em>
<em>Total no. of marbles in the bag= 7+8=15</em>
As we know that,
Probability( of a random event A)= 
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=
