If two same events have to occur randomly every month (30 days), and only one event can occur per day, what is the probability of The two events occurring on the last two days of the 30 day period ?

thank you

There are \(\displaystyle \dbinom{30}{2}\) ways for those two identical events can occur in a month.
How many ways can they occur on the last two days?
