List the letters of the two choices below which have equal probabilities of success, separated by a comma. A standard deck of cards has 12 face cards and four Aces (Aces are not face cards).
A. drawing a red seven out of a standard 52 card deck given it�s not a face card or an Ace.
# of red 7's: 2
# not face or ace: 52-16 = 36
Probability: 2/36 = 1/18
------------------------------------
B. drawing a five out of a standard 52 card deck given it�s not a face card or an Ace.
Probability: 4/36 = 1/9
-------------------------------
C. rolling a sum of 4 on two fair six sided dice:: 3/36 = 1/12
-------------------------------------------------------------------
D. rolling a sum of 5 on two fair six sided dice: 4/36 = 1/9

Ans: B and D
