Answer:
If you flip 2 coins the possible results are:
H1 H2, H1 T2, T1 H2 and T1 T2 there no other possibilities
So the probability of H H is 1/4 as tis he probability of T T.
The probability of an H and a T is 2/4 or 1/2.
The total probability adds to 1 as it must.
So, theoretically, in 100 tosses you should get
25 HH, 25, TT and 50 HT.
This will differ from the experimental values because the experimental results occur randomly.
In more advanced probability theory, the results are expected to form
what is called a bell curve which would be the expected results of a very large number of tosses, with different curves for HT and HH. Taking HH
one would expect most of the results to cluster around the middle of the
curve, which is the top of the bell with a probability of 1/2. Large variations from the expected result would form the lower portions of the bell or be in one of the tails of the curve.
