Question 392036
 Please! help my son this home work,I don't understand word either
two cards are drawn from a standard deck of cards .Find probability
P(both either black or an ace)
If you mean both black, or one card is an ace and other is not relevant:
Both black:
= (13/52)*(12/51) = 1/17
One ace:
= (4/52) + (4/51) = 412/2652 = 103/663
Since it's either, add them
1/17 + 103/663 = 2414/11271
Some big numbers, but it's just adding fractions.
------------------
P(both jack  or both face cards)
Jacks:
(4/52)*(3/51) = 1/221
Face cards (J, Q or K):
(12/52)*(11/51) = 11/221
Since it's either,
= 1/221 + 11/221 = 12/221
