A coin is tossed 5 times. Calculate the following probabilities:
a) Head appears on the 1st toss:: 1/2
-------------------------------------------
b) Head appears on both the first and second tosses:: (1/2)^2 = 1/4
-------------------------------------------
c) Head appears once during the 5 tosses:: 5C1(1/2)^5 = 5/32
---------------------------------------------
d) Head appears more than twice during the 5 toss::
5C3(1/2)^5 + 5C4(1/2)^5 + 5C5(1/2)^5
= (10+5+1]/32
= 1/2
