A person tosses a coin 19
times. In how many ways can he get 12
heads?
The number of ways a person can get 12 heads out of 19 tosses can be calculated using the binomial coefficient formula:
C(n, k) = n! / (k! * (n-k)!)
where n is the total number of tosses and k is the number of heads.
Therefore, the number of ways the person can get 12 heads out of 19 tosses is:
C(19, 12) = 19! / (12! * (19-12)!) = 50388
So, the person can get 12 heads out of 19 tosses in 50,388 ways.
