So to find probability you would have to add together all of the marbles in the bag (7+8+9=24) and then find the fractional probability of drawing blue marbles out of all the marbles in the bag. So 9/24
The probability of choosing a blue marble when one marble is drawn is 17/23.
What is probability?
The probability of an event occurring is defined by probability.
Probability is also called the chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.
In our daily time, there are several instances in the everyday world where we may need to draw conclusions about how everything will turn out.
Total number of marbles = 7 + 8 + 9 =24
one marble is drawn then remaining = 23
If drawn marble were green then
No. of green marble = 8
Probability of drawing green marble = 8/23.
If drawn marble were not green then
No. of green marble = 9
Probability of drawing green marble = 9/23
Since probability add in the cases so
The probability of drawing green marble a second time will be
8/23 + 9/23 = 17/23 hence, it will be correct answer.
