Answer:
5/7
Step-by-step explanation:
There are 7 different days of the week.
5 are weekdays: Monday, Tuesday, Wednesday, Thursday, Friday
2 are weekend days, which are not weekdays: Saturday, Sunday
p(event) = (number of desired outcomes)/(total number of possible outcomes)
The desired outcomes are all the weekdays. There are 5 of them, so the number of desired outcomes is 5.
The total number of possible outcomes is 7 since there are 7 different days in a week.
p(weekday) = 5/7
