The first flip can obviously return only H or T.
Suppose the coin lands on H. This means that every following string is possible (and thus part of the sample space)
So, there are 16 such strings, because every flip has two possible outcomes.
Suppose now the coin lands on T. Like before, we add to the sample space the following strings:
And thus there are 4 such strings, because we have two choices for each of the two flips.
So, the sample space has 20 outcomes:
H - HHHH
H - HHHT
H - HHTH
H - HHTT
H - HTHH
H - HTHT
H - HTTH
H - HTTT
H - THHH
H - THHT
H - THTH
H - THTT
H - TTHH
H - TTHT
H - TTTH
H - TTTT
T - HH
T - HT
T - TH
T - TT
In order to solve this we will have to apply PEMDAS rule which is as follows:
P
Parentheses first
E
Exponents (ie Powers and Square Roots, etc.)

7+8(3.2.2)
Step 1:
Here we will solve the parenthesis first :
multiplying 3.2.2 =12
so we have 7+8(12)
Step 2:
now we multiply 12*8 here
12*8=96
7+96
Step 3:
addition of 7 and 96 gives us 103
Answer : 7+8(3.2.2) = 103

4/5. To divide a fraction by a fraction you would flip the second fraction, simplify if possible and multiply like normal.
1/2 x 8/5
1/1 x 4/5
4/5 :)
Secant
Remember it by linking the third letter:
SeCant = 1/Cos
CoSecant = 1/Sin
CoTangent = 1/Tan
