Question

A person is to pick a marble at random from a bag containing $8$ red marble, $6$ while marbles, $2$ blue marbles and no other marbles.

• A. If the quantity in Column A is greater
• B. If the quantity in Column B is greater
• C. If the two quantities are equal
• D. If the relationship cannot be determined from the information given

Answer 1

Answer: (C)

If the two quantities are equal

There are $8$ red marbles, $6$ white marbles, $2$ blue marbles.

Probability of selecting a red marble is $\frac{8}{(8+6+2)}=\frac{8}{16}=\frac{1}{2}$
Probability of selecting a white or blue marble is $\frac{(6+2)}{(8+6+2)}=\frac{8}{16}=\frac{1}{2}$.
Therefore both quantities are equal.
So, the correct option is $C$.
