Out of the 12 numbers above, 5 (in bold type) are 100 or less.

5/12 = 0.41666...

Answer: 0.417

The probability that an employee selected randomly has a birthday in the first 100 days is 0.417

Recall :

Probability = required outcome / Total possible outcomes

Total possible outcomes :

  • 344 180 274 358 64 121 32 96 151 275 93 49 = 12

Required outcomes :

  • Values less Than or equal to 100 : 64, 96, 32, 93, 49 = 5

Therefore,

  • P(first 100 days) = 5 / 12 = 0.41666

Therefore, the selection probability is 0.417
