Option C is the answer.

Step-by-step explanation:

There are some marbles in a jar

Blue -  7  marbles

Green -  5 marbles

Red  - 4 marbles

Total = 16 marbles

So the probability that first marble drawn is red =

Now without replacing you selected another marble, So the probability that second marble is red =

=

=  

P = × =

The probability of selecting a red marble and then another red marble is

.
