There is 1 Red, 2 Greens, 3 Yellows, and 4 Blues.
Define Theoritical Probability
Theoritical Probability is what should happen.
Red 1 - 10% Green 2 - 20% Yellow 3 - 30% Blue 4 - 40%
Define Experimental Probabiltity
Experimental Probability is what really happens.
* The more you experiment the close you get to theoritical probability.
Which Italian Insects Often Fall in Love?
1. Each time you spin this spinner how many likely outcomes are there?
likely outcomes = TOTAL POSSIBLE OUTCOMES = 10
likely outcomes = TOTAL POSSIBLE OUTCOMES = 10
2. Find each probability if you spin the spinner once.a. P(even number)
= 4/10 because in the spinner they're are 4 even numbers and the total possible outcome is 10. You can also say 2/5 because it is the same as 4/10 it is just simplified. You can get 2/5 by dividing the numerator and denominator by 2. Lastly, you can say 40% because that is the percent of the fraction. You get that by dividing 4 and 10 which equals 0.4 then you x it by 100 and it will = 40%.
b. P(odd number)
= 5/10 because in the spinner they're are 5 odd numbers and the total possible outcome is 10. You can also say 1/2 because it is the same as 5/10 it is just simplified. You can get 1/2 by dividing the numerator and denominator by 2. Lastly, you can also say 50% because that is the percent of the fraction. You get that by dividing 5 and 10 which equals 0.5 then you x it by 100 and it will = 50%.
c. P("A")
= 1/10 because in the spinner there is only one "A" and the total possible outcome is 10. You can also say 10% because that is the percent of the fraction. You get that by dividing 1 and 10 which equals 0.1 then you x it by 100 and it will = 40%.

3. If you spin the spinner 100 times, about how many times would you expect it to stop on:
a. an even number b. an odd number.
It will be 50 for both, because it is based on 100 and there is only two possible outcomes. You get 50 by dividing 100 by 2 and it will equal 50.
