A number is chosen at random from the numbers\[3,\text{ }2,\text{ }1,\text{ }0,\text{ }1,\text{ }2,\text{ }3\].

What will be the probability that square of this number is less then or equal to 1?

Answer:

Possible outcomes {\[3,\text{ }2,\text{ }1,\text{ }0,\text{ }1,\text{ }2,\text{ }3\]}, \[n=7\] and only three numbers \[1,\text{ }0,\text{ }1\] fall under given condition so,

Required probability \[=\frac{3}{7}\]
