262/365

Step-by-step explanation:

So as you can see there is no more information aout Kay on her birthday, so the chances of her birthday being on a week day is given by the total number of the weekdays of the year between the total number of days in a year, so in 2019 there are 262 weekdays, divided by 365 you get the probability that Kay's birthday falls on a weekday.

262/365=,7178=71,78%

So the probability of Kay's brithday falling on a week day will be 71,72%
