Answer:

C

Step-by-step explanation:

If you do 5+1+2=8 then it has to be out of 8. The only option that is out of 8 is c, and if you have 5 blue then the probability is 5 blue/8 marbles in the bag.

The probability of that second marble is blue is 5/8.

What is probability?

Probability is "possibility that deals with occurrence of random events".

According to the question,

Number of blue marbles = 5

Number of pink marbles = 1

Number of red marbles = 2

Total number of marbles =  5 + 1 + 2 = 8

Formula for Probability P(E) = [tex]\frac{Number of favourable events }{Total number of events}[/tex]

Probability of getting that second marble is blue = 5/8.

Hence, the probability of that second marble is blue is 5/8.
