Question

A number is chosen at random from the numbers - 3,-2,-1,0,1,2,3. What will be the probability that
square of this number is less than or equal to 1.​

Answer 1

Answer:

3/7

Step-by-step explanation:

Our Sample Set is {−3,−2,−1,0,1,2,3}

The squares of these numbers will be {9,4,1,0,1,4,9} respectively.

So on choosing one number at random we may satisfy the requirement thrice, i.e. if the chosen numbers are, −1.0, or 1

So, the probability p(A)=  

(sample space) /(total no. of possible outcomes) = 3/7
