Question

probability......???? ​

Answer 1

so,

total days in a year = 365

total possible outcome (birthday be same) = 1

so, probility of different birthday = $\frac{365-1}{356}$

= 0.96986

Probability of same birthday

$\frac{1}{365}$

= 0.0027

Answer 2

Answer:

Step-by-step explanation:

Ans¹:- No. of all possible outcomes of days. = 365

No. of favourable outcomes 365-1=364

P(different birthdays)= 364/365 =0.9972

Ans²:- No. of all possible outcomes of days. = 365

No. of favourable outcomes =1

P(same day) = 1/365=0.002739
