    PROBLEM 1a.

    Odds in favor are given as the ratio of favorable outcomes to *unfavorable* outcomes.

    There are 3 ways to roll a sum of 4 (1+3, 2+2, 3+1)

    There are 33 other ways to roll a different sum (36 - 3 = 33)

    So the odds in favor are 3:33

    However that can be reduced.

    Answer:

    1:11

    PROBLEM 1b.

    There are 2 ways to draw a black ace (Ace of spades and Ace of clubs)

    There are 50 other cards that aren't black aces.

    So the odds in favor are 2:50

    Again, that can be reduced.

    Answer:

    1:25

    PROBLEM 2:
