*Refer to "sheet 2" of the attached table

2) From the adjusted table of 183 consecutive days, we can use the special "if" function of Excel to count.

The number of Rain days is 65

The number of days on which it rained given that it rained the previous day is 28.

Then p-hat(R) = 28/65= 0.4308

3) From the adjusted table, we can count the number of days when it did not rain is 118

The number of days on which it rained given that it did not rain ...
