Given : in group of 3 students, the probability that the 2 students have the same birthday 0.008.
To find : What is the probability that the students not having the same birthday
Solution:
Probability that 2 students have same birthday = 0.008
Probability that 2 students does not have same birthday = P
P (A) + P(A') = 1
=> 0.008 + P = 1
=> P = 1 -0.008
=> P = 0.992
Probability that 2 students does not have same birthday = 0.992
