Answer:
Step-by-step explanation:
Probability of getting a 7 + Probability of not getting a 7 = 1.
Odds against drawing a 7 = Probability of not getting a 7.
We could calculate the probability of getting a 7 and subtract 1 from it to get the answer.
There a four sevens in a deck of card, one of each kind.
Probability of getting a 7 =
P(not getting a 7)
4/15
x 12x - 6 3x + 3 6(2x - 1)
1 6 6 6
2 18 9 18
3 30 12 30
