You roll a die four times. What is the probability that it will show an even number the first three times, then a one the last t
mezya [45]

A die has six sides so you have a *blank*/6 chance of getting a certain number.

Since there are 3 even numbers on a die and 3 odd numbers. So the probability of rolling a even number would be:

3/6 or 1/2 or 50%

There is a one, one on a die so your chance of rolling a one the last time would be:

1/6 or about 16%

Hope this helps :) If you have any more questions just ask!
