According to a survey, 32% of drivers tailgate other vehicles before passing them (thinking it will incite them to speed up). Consider 45 drivers selected at random. Use a normal approximation to find the probability that:
(a) at least 17 drivers tailgate? (Use only 3 decimal places)
(b) more than 9 but less than 25 drivers tailgate? (Use only 3 decimal places) ans_a is 0.251

A golf ball is selected at random from a golf bag. If the golf bag contains 8 type A balls, 5 type B balls, and 3 type C balls, find the probability that the golf ball is not a type A ball.
SUM OF POWERS:
you are given a list of integers L of size N. write a program to compute the value of SUM
SUM=x1pow1+x2pow2+x3pow3+-----+xNpowN
where xi concatenated with powi is the i th element of the list L and powj is single digit number
input:
The input contains space-separated N integers
Explanation: L=[25]
x1=2 ,pow1=5
SUM=2^5=32
i/p: L=[132,301]
x1=13,pow1=2
x2=30,pow2=1
SUM=13^2 +30^1=199
