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
Check your understanding :
1.
Which of the following is an experiment?
2.
Which of the following is an outcome?
3.
Which of the following experiments does NOT have equally likely outcomes?
4.
What is the probability of choosing a vowel from the alphabet?
5.
A number from 1 to 11 is chosen at random. What is the probability of choosing an odd number?
