A baby born in 2011 is randomly selected. What is the probability that the baby was born in February?

The probability of an event is calculated by dividing the number of favorable outcomes by the total number of outcomes.

In this case, we are looking for the probability that a baby born in 2011 was born in February.

1. There are 12 months in a year, so the total number of outcomes is 12.

2. The number of favorable outcomes is 1, because we are only interested in one specific month: February.

So, the probability (P) that a baby born in 2011 was born in February is calculated as follows:

P(February) = Number of favorable outcomes / Total number of outcomes = 1 / 12 = 0.0833

So, the probability that a baby born in 2011 was born in February is approximately 0.0833, or 8.33%.
