Answer 1

Answer:

The probability that the 2 students have the same birthday is 0.008.

Step-by-step explanation:

▪️Let E be the event of having the same birthday.

▪️P(E) = 0.992⇒ P(E) + P(not E) = 1⇒ P(not E) = 1 – P(E)⇒ 1 - 0.992 = 0.008

▪️The probability that the 2 students have the same birthday is 0.008

Answer 2

Given:

Total number of students = 3

Students who do not share same birthday = 2

Probability = 0.008

To Find:

Probability of having the same birthday

Solution:

Probability of two students not having same birthday = 0.008

Probability = 1 - Students having the same birthday

0.008 = 1 - Students having the same birthday

P ( same birthday) = 1 - 0.008

P ( same birthday) = 0.992

Answer: The probability of having the same birthday is 0.992
