It would be a 100% probability or 1 on a scale of 0 to 1 (where 1 is a certainty). Some would argue though, that nothing can ever be 100% certain, e.g what happens if the world gets wiped out by a massive asteroid half way through the month, killing everyone. The chances are low, but there nonetheless...

You randomly select a month of the year What is the probability that you select a month with 28 or 30 days in it?
First we don't consider leap year There is 1 month with 28 days: february There are 4 months with 30 days: april, june, september, november So the probability to select a month with 28 or 30 days is (1+4)/12 = 5/12 If the year is a leap year then the probability is 4/12

If a coin is tossed for 30 times what is the probability of having no heads?
No heads means that every toss lands tails. (0.5)30= 9.3 x 10-10 Note that 109 = 1 trillion, so the probability can be stated this event is likely to occur about 9 times in 10 trillion tosses.
A class has 30 students what is the probability that nobody in the class have same birthday count one year as 365 days?
ok let's try this! on any given date, probability that there is a student with a birthday is 30/365, so prob. that two students have that birthday is (30/365)^2. Tell me if I'm wrong, somebody! So the problem that this does NOT happen is 1-(30/365)^2 which is 0.9932445... I'm not sure about this next bit: there are 365 days in which this probably won't occur, does that make a difference?
