### E-49 (questions 1-6)

l. Find each probability if you spin the spinner once.

PO (Possible outcomes)

-----------

TPO (Total Possible Outcomes)

1) P (red)

As a fraction- 1/5

To get a percentage: 1 divided by 5= 0.2 x 100= 20%

2) P (green)

As a fraction- 1/5

Percentage: 20%

3) P (blue or white)

As a fraction- 2/5

Percantage- 40%

4) P (not yellow)

As a fraction- 4/5

Percentage- 80%

5) P (not red)As a fraction- 4/5

Percentage- 80%

P (blue or red or yellow)

As a fraction- 3/5

Percentage- 60%

My own question:

You go to a party and there are 80 party favours in a bag. 5 are lasers, 10 are stuffed toys, 25 are kazoos, 20 are bags of candy and 20 are computer games. What is the probability of pulling out anything besides the kazoos?

5 + 10 + 20 + 20= 55

As a fraction- 55/80

Percentage- 55 divided by 80= 0.6875

0.6875 * 100= 68.75%
