A bag contains 4 red, 5 blue, and 6 green marbles: One blue marble is selected and NOT replaced. If a 2nd marble is drawn, what is the probability that the 2nd marble drawn is a blue marble? Write your answer as a simplified fraction.

2/7

Step-by-step explanation:

To find the this first you need the total number of marbles minus one since the blue marble was taken.

4+5+6-1=14

after one blue marble being picked there are 4 blue left, so the fraction is

4/14 and after being simplified it is 2/7

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
