Question

What will be the probability that two friends have the same birthday date in a normal year ?

• A. $\frac{1}{73}$
• B. $\frac{1}{365}$
• C. $\frac{7}{365}$
• D. $\frac{12}{365}$

Answer 1

The correct option is B $\frac{1}{365}$

Number of days in a year = 365
Therefore, total possible outcomes = 365

If they have birthday on same day, then number of favourable outcomes =1

Therefore, required probability $=\frac{1}{365}$
