Answer:
7/15
Step-by-step 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)= [tex]\frac{Favourable\ no.\ of\ elementary\ events}{Total\ no.\ of\ elementary\ events}[/tex]
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=[tex]\frac{7}{15}[/tex]
