Answer:
r=2/3
Step-by-step explanation:
22 total tokens
15/22 is the probability you won’t draw a red
first convert 0.88 to degrees
so arcsin(0.88) = 61.642 degrees
Arcsin on a calculator is sin^-1
then to convert to radians divide degrees by 180 and multiply that by PI
so (61.642/180) x PI = 1.076 radians
I would say the amount used would be at least 50 gallons because it makes most sense. Hope I helped :))
