The total number of marbles
5+6+4 = 15 marbles
First we find the probability of a blue marble. There are 6 blue marbles
P(blue) = blue/total = 6/15 = 2/5
We put the marble back so there are still 15 marbles in the bag
Then we find the probability of a red marble. There are 5 red marbles
P(red) = red/total = 5/15 = 1/3
Since we put the marble back, they are independent events, and we can multiply the probabilities.
P(blue, then red) = 2/5*1/3 = 2/15
hope this helps
Using mid-term break
n-6=0 OR n+7=0
n=6 OR n= -7
