Given,
Number of people chosen randomly =2
To Find,
The probability that 2 people chosen at random were born on the same day of the week =?
Solution,
Total number of days in a week = 7
Probability of choosing a day from a week = 1 / 7
Therefore, the probability that 2 people chosen at random were born on the same day of the week = 1 / 7 * 1 / 7
The probability that 2 people chosen at random were born on the same day of the week = 1 / 49
Hence, the probability that 2 people chosen at random were born on the same day of the week is 1 / 49.
