Answer: first blank is Alternate Angle Theorem,
second blank is angle ADB≅ angle CDF.
Define the events
A = spinning any number but 4 (ie not getting 4)
B = flipping tails
For each event, the probabilities are:
P(A) = 4/5 because there are four numbers that aren't "4" out of five numbers total
P(B) = 1/2 assuming the coin is fair and each side is likely
P(A and B) = P(A)*P(B) is possible because the two events A and B are independent
So,
P(A and B) = P(A)*P(B)
P(A and B) = (4/5)*(1/2)
P(A and B) = (4*1)/(5*2)
P(A and B) = 4/10
P(A and B) = 2/5
The answer as a fraction is 2/5
In decimal form, the answer is 0.4
A squared plus B squared equals C squared. So 16x16=256. 63x63=3,969. 3,969+256=4,225. The square root of 4,225 is 65. 65 is the missing side.
