1. List the sample space for this problem.


2. Which outcome (or outcomes) of the sample space composes the event?


3. Express the probability of Kay’s birthday falling on a weekday as a fraction and as a decimal.


4. Describe the probability of Kay’s birthday falling on a weekday as impossible, unlikely, neither likely nor unlikely, likely or certain. Justify your response.

Answer 1

okay so you take the number of weekdays to the number of weekends the ratio is 5:2 one month, which usually has 30 days which is 4 weeks tops so that is about 21 week days and and 9 weekends then times both by 12 you get 108 weekends and 252 weekdays i know that only equals 360 but this is a rough estimate so write that as a fraction 3/7 so there is a third that it will be on a weekday
