Question

A number x is chosen at random from the numbers −3, −2, −1, 0, 1, 2, 3 the probability that | x | < 2 is

(a) $\frac{5}{7}$

(b) $\frac{2}{7}$

(c) $\frac{3}{7}$

(d) $\frac{1}{7}$

Answer 1

GIVEN: A number x is chosen from the numbers −3, −2, −1, 0, 1, 2 and 3

TO FIND: Probability of getting

Total numbers are 7

Number x such that are −1, 0, 1

Total numbers x such are 3

We know that PROBABILITY =

Hence the probability of getting a number x such thatis equal to

Hence the correct option is
