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)
Answer:
89.6%
Step-by-step explanation:
The probability a random person shares your birthday is 1/365, or 0.27%. That means the probability that they don't share your birthday is 364/365, or 99.73%.
So the probability that you meet 40 people who don't share your birthday is:
P = (364/365)^40
P = 89.6%
