A: 3 out of 36 possibilities so \[\frac{3}{36}=\frac{1}{12}\]

B is worded funny, but i guess we are supposed to think it means you know it is not a face card or an ace, so there are 12 face cards, 4 aces for a total of 16 and therefore out deck has 36 cards, 4 sevens so \[\frac{4}{36}=\frac{1}{9}\] for B

eleven has 2 possibilities out of 36 so \[\frac{2}{36}=\frac{1}{18}\] no matches yet!

probability you roll a seven on a pair of dice is \[\frac{1}{6}\] so it is up to the last one

ok i made a mistake. B says "black 7" not 7 so it should be \[\frac{2}{36}=\frac{1}{18}\]

so B and C are the same. now lets try E again 36 cards left in the deck, and 4 are threes so this time it is \[\frac{4}{36}=\frac{1}{9}\] i will let you find the matches
