When you say "I want to make sure that I solved them correctly,
the tasteful, less suspicious thing to do is to list YOUR solutions,
so that the responder can either say "that one's correct" or else
show you how to do it.

1). HHH
HHT
HTH
HTT
THH
THT
TTH
TTT
a). The probability of each one is 1/8 = 12.5% .
b). There's only one of those on the list. 12.5%
c). 12.5%
d). There are 3 ways that can happen. 3/8 = 0.375 = 37.5%

2). There are 16 possible outcomes.
a). Prob of each outcome is 1/16 = 0.0625 = 6.25% .
b). There's only 1 way that can happen, so it's 6.25% .
c). There's only 1 way that can happen, so it's 6.25% .
d). There are 6 ways that can happen. Prob = 6/16 = 37.5%
e). There are 4 ways that can happen. Prob = 4/16 = 25%

To find the value of the angle we start with tan(theta)= o/a now fill in variables tan(theta)= 39.05/18 then we have to move tan to the other side so we get theta = tan^-1(39.05/18) this will give us theta = 65
