It’s C since you have to add the amount
Which will be 5+7+4= 16
And when you look at the fractions that is the only answer that contains 16

Answer:

1/12

Step-by-step explanation:

Total number of marbles = 5+7+4 = 16 marbles

Probability of picking a red marble = 5/16

Because the red marble is not returned back after being picked up, the total number of marbles is now 15.

Now,

Probability of picking a yellow marble = 4/15

The probability of picking a red and yellow marble will be the product of these two probabilities which will = 5/16 x 4/15 = 1/12
