The possible combinations we can get are:
H H
H T
T H
T T
Less than 2 H is 3 out of 4. So thats 75% probability.
More than 1 T is 1 out of 4. So thats 25% probability.
Atleast 1 Head is 3 out of 4. So thats 75% probability.
At most two heads is valid for all cases as you can not get more than 2 tails. Hence the last one is 100% probability
H H
H T
T H

Less than 2 H is 3 out of 4. So thats 75% probability.
More than 1 T is 1 out of 4. So thats 25% probability.
