Hello!
First you have to find the probability of a pulling a penny
To find this you put the amount of pennies over the amount of coins
There are 12 coins and 5 pennies
This is a 5/12 probability
Next you have to find the probability of then pulling out a quarter
Since you already took out a coin the total amount is now 11
The probability is 4/11
You multiply the two probabilities together to get the probability of them happening one after antoher
5/12 * 4/11 = 5/33
The answer is D)5/33
Hope this helps!
