Answer:
417/2921
Step-by-step explanation:
6/23-15/127
- First, we have to figure out the lcm which is 2921.
- Multiply the denominators so make them 2921.
(127) 6/23 - 15/127(23)
762/2921 - 345/2921
- Subtract the numerators.
417/2921
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%
