Fun Learning in Probabality







What is probability?
learn how to find the probability of random phenomena/ event.


Probability Of An Event
P(A) =  The Number Of Ways Event A Can Occur
The total number Of Possible Outcomes


To learn probability, you can learn directly with experiment like tossing coin, die and etc.
Such as  in the video below.


Experiment 2:   A single 6-sided die is rolled. What is the probability of 1 outcome? What is the probability of rolling an even number? of rolling an odd number?

Outcomes:   The possible outcomes of this experiment are 1, 2, 3, 4, 5 and 6.
Probabilities:  
P(1)  =  # of ways to roll a 1  =  1
total # of sides 6

P(even)  =  # ways to roll an even number  =  3  =  1
total # of sides 6 2
P(odd)  =  # ways to roll an odd number  =  3  =  1 
total # of sides 6 2

You can also use games to learn probability. I think  you can more enjoy with this way to study about probability. Check to this link for gameshttp://www.youtube.com/watch?v=zzaMZ4CHWLc
