Sure! Probability is the likelihood of something happening.
Mike, pay attention.
What's an example?
Might as well hear what the nerd has to say.
If you take out a red candy out of a bag of 4 different color candies, the probability is 1/4. 1 red candy out of 4 different color ones. Probability is expressed as a fraction.
4x-7=5, numbers, variables and operators used together to show the value of something is an expression
But what if there are two or more events happening after each other?
That's what we call compound probability. It's the opposite of simple probability, with only one event.
I've heard of two types of compound probability. What are they?
They are independent and dependent.
Independent probability is when there are two or more events happening that do not affect each other. And dependent probability is when the events do affect each other.
Wow! Now if I get a probability problem in math class, I'll know what to do! Thanks!
Imagine you have that bag of candies. You take out one red one, put it back, and then take a blue one. Each time you take out 1 candy out of 4 total ones. 1/4. Multiply those probabilities together, and you get 1/16.
However, let's say you didn't put back the red candy. Now, if you take a blue candy, it is 1/3, since one candy out of 4 total ones is gone. 1 blue candy over 3 total ones. Multiply 1/4 times 1/3 and you get 1/12.
