Question
The range of the function f(x) = |x - 1| is:
- $\big(-\infty,0\big)$
- $\big[0,\infty\big)$
- $\big(0,\infty\big)$
- $\text{R}$
Solution:
$\text{f(x)}=|\text{x}-1|\geq0\ \forall\text{ x}\in\text{R}$
Thus, range $=\big[0,\infty\big)$

Toss a fair coin 3 times in a row, how many elements are in the sample space?
A five digit number divisible by 3 is to be formed using the numbers 0, 1, 2, 3, 4 and 5 without repetitions. The total number of ways this can be done is.
[Hint: 5 digit numbers can be formed using digits 0, 1, 2, 4, 5 or by using digits 1, 2, 3, 4, 5 since sum of digits in these cases is divisible by 3.]
