Question

A number is chosen at random from the numbers -3 -2 -1 0 1 2 3 what is the probability that the square of these numbers is less than or equal to 1?
​

Answer 1

Answer:

total no. = 7

Square of each no.

(-1)² = 1

(-2)²=2

(-3)²=3

0²=0

1 ²=1

2²=4

3²=9

therefore, there are three Numbers  less than or equal to one,

So, Probability = No. of outcomes / total no. of out comes

= 3/7

therefore the probability is 3/7
