Question:
A number x is chosen at random from the numbers -3,-2,-1,0,1,2,3 the probability that |x| < 2 is____?Â
Answer:
From the difinition of modulus,
Modulus of a number or absolute value of a number is either zero, or positive but never negative.
So, |-3| = 3, |-2| = 2 and |-1| = 1
Now, numbers which are less than 2 are: -1, 0, 1
So, P(|x| < 2) = 3/7
