Sarah has gone four weeks. micah has been recording the daily high temperature. during that time, the high temperature has been greater than 45f on 20 out of 28 days. what is the experimental probability that the high temperature will be below 45f on the twenty-ninth day?

The experimental probability that the high temp will be below 45 F on the 29th day is, 4.5 out of 29 days, that is because 20 of the days have had lower temperatures, so they left 9 days of and from those 9 days, they could be lower or greater that 45F (50% each side), that is:
4.5/29 = 0.155 = 15.5%
that is the exp probability
