Probability - Problem 2
I bet you money when you are doing your home work about probability there’s going to be something about rolling a dice, sometimes they call it a number cube. The important thing to keep in mind is that all 6 spaces are equally likely to be rolled. That’s where I can use my probability formula where I’m going to put number of successful outcomes on top of number of possible outcomes.
So here what’s the probability of rolling a dice and getting an even number? Okay so think about the faces of a dice our options are 1 2 3 4 5 and 6. The even numbers there are 2 4 or 6 right? We don’t care exactly what those numbers are, we just care that they are three of them. There are three successful outcomes out of 6 possible sides on that dice. I’m going to write p of even that means probability of rolling an even number is 3/6.
Reduce that fraction to ½ or you could turn into a decimal or even the percent. It’s totally up to you how you want to write your answer just make sure you are reading directions carefully incase your textbook or your teacher wants a specific format.
