suppose you roll two dice, what is the probability of rolling a sum of 11
There are thirty-six different ways the dice can land. There are two different ways the dice can total eleven. Two out of thirty-six is about one of eighteen.
You might need a calculator if you need a decimal approximation.
you spin the pointer on the spinner, find the possibility the spinner will land on a 1 the spinner numbers are 1 2 3 and 4
If the numbers are evenly spaced on the spinner, the chance is one in four, or about .25. Of course, the disk might be divided unevenly (no way to know based on what you said in the problem) to give another probability.
Ohh wooaah [x3] You know you love me, I know you care Just shout whenever, and I'll be there You are my love, you are my heart And we will never ever ever be apart Are we an item? Girl, quit playing We're just friends, what are you saying? Say there's another and look right in my eyes My first love broke my heart for the first time And I was like...

I'm gone
how'd you figure that out so i can learn
There are four ways it might turn out. You are "successful" if it gets one of those ways. So the number of ways to be "successful" divided by the total number of ways it can turn out gives the probability.
How was that?
okay i got it so the next one has one dice and it wants to know the probability of rolling a multiple of 2 would that be 1 out of 6?
