Answer: The probability is 2/7.
Step-by-step explanation:
Ok, suppose you meet a random person.
The possible days in which that person was born are the seven days of the week, so the total number of outcomes is 7, and we will assume that the probability is evenly distributed for all the days.
Now, we want to calculate the probability that this person was born on a Monday or a Friday.
So we have 2 possible outcomes out of 7.
Then the probability will be equal to the quotient between number of of outcomes that meet the conditions (Monday and Friday, 2 outcomes) and the total number of outcomes (7)
P = 2/7
