there are 56 % chance ok plz brainest

Answer 2

Answer:

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

Step-by-step explanation:

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

To find : What is the probability that the 2 students have the same birthday?

Solution :

We know that, The sum of the probabilities is 1.

Let the probability of students not having the same birthday be P(E),

Then the other be P(E')

We have given, P(E)=0.992

P(E)+P(E')=1P(E)+P(E

′

)=1

0.992+P(E')=10.992+P(E

′

)=1

P(E')=1-0.992P(E

′

)=1−0.992

P(E')=0.008P(E

′

)=0.008

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