Certain.
The probability is 1. It is always raining - any time of the day or night, any day of the year - somewhere on Earth.
Considering the fact that a non-leap year having 28days in February will definitely have 4 Tuesdays , we have to find the probability that the 29th day of a leap year (2008) is also a Tuesday. This probability is 1/7 i.e 1 out the probable 7days in a week ! Well this said, this question is void in a sense knowing that we are in 2010 and that February 2008 had 5 Fridays and therefore the probability of 5 Tuesdays is ZERO as of 2008 !
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
The probability of a tornado hitting Kansas is 100%. Dozens of tornadoes occur in Kansas every year.

The probability is 1. It is always raining - any time of the day or night, any day of the year - somewhere on Earth.
As of 2011, the next time February 29 will occur is in 2012.
February 29th happens once every 4 years. So yes. If you just celebrated your birthday on february 29th, you wont see it the year after. or the next 2 ones. February 29th will happen next year.(2012)
There are february 29th every 4 years except if the year is divisible by 400 So the probabilty that a year will have a february 29th is 1/4-1/400 = 99/400 = 0.2475
The probability is zero since Feb 2008 had 4 Tuesdays.
The probability of a given 80-year-old person dying in the next year is 27%.
Considering the fact that a non-leap year having 28days in February will definitely have 4 Tuesdays , we have to find the probability that the 29th day of a leap year (2008) is also a Tuesday. This probability is 1/7 i.e 1 out the probable 7days in a week ! Well this said, this question is void in a sense knowing that we are in 2010 and that February 2008 had 5 Fridays and therefore the probability of 5 Tuesdays is ZERO as of 2008 !
On every day in February of any year it would have rained somewhere in the world.
