PROBABILITY
Theoretical Probability is the ratio of favourable outcomes to the number of total possible outcomes.
There's 1 red, 2 green, 3 yellow and 4 blue gumballs. The total possible outcome is 10.
In percentage, there's 10% of getting red, 20% of green, 30% of yellow and 40% of blue, that makes a 100%.
Experimental probability is the ratio of favourable outcomes to the total number of trials.
red= 14/100 green=20/100 yellow=31/100 blue=35/100
The more you experiment the closer you get to theoretical probability.

2.) Find each probability if you spin the spinner once. 
a. P (even number) = 4/10 because there are 4 even numbers out of 10.
= 2/5, equivalent fraction of 4/10 --> 4/10 divided by 2=2/5
= 40%, the percentage --> 2 divide by 5 or 4 dived by 10=0.4 x 100=40%
b. P (odd number) = 5/10 because there are 5 odd numbers out of 10.
= 1/2, equivalent fraction of 5/10 --> 5/10 divide by 2=1/2
= 50%, the percentage --> 1 divide by 2 or 5 divide by 10=0.5 x 100=50%
c. P ("A") = 1/10 because there is only 1 "A" out of 10 .
=10%, the percentage --> 1 divide by 10=0.1 x 100=10%
5.)If a raindrop falls on this set of tiles. How many equally likely outcomes are there?
= there are 25 outcomes
6.) Find each probability if a raindrop falls on the tiles.
a.) P (falling on black) = 9 out of 25 because there are 9
black tiles
= 9/25 = 0.36 x 100=36% as percentage
b.) P ( falling on white) = 16 out of 25 because there are 25
white tiles.
= 16/25 = 0.64 x 100=64% as percentage
c.) P (falling on green) = there is none falling on green.
= 0/25 = 0%
