What is the theoretical probability that the spinner lands on red? Red: 4
Blue:10
Green:6

1/5

Step-by-step explanation: You add 4+10+6 to get 20. So the probability that the spinner lands on red would be 4/20. If you need it simplified  you take 4 and divide it by 4 to get 1, then you would divide 20 by 4 to get 5. that would leave you with 1/5.

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
