It is given that in a group of 3 students, the probability of 2 students not having the same birthday is 0.992. What is the probability that the 2 students have the same birthday?

Probability that two students are not having same birthday P (not E) = 0.992
Probability that two students are having same birthday P (E) = 1- P (not E) = 1 – 0.992 = 0.008
