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:

Step-by-step explanation:

Total 7 numbers are given from -3 to +3;

Condition for probability = square of number is < 1 or = 1;

(-1)^2 = 1

(0)^2 = 0

(1)^2 = 1

Only three possible outcomes based on the given condition ;

So probability = 3/7

Answer 2

Answer: 3/7

Step-by-step explanation:

There are seven integers given from negative 3 to positive 3.  

When squaring any integer it will always give a positive answer.  

So squaring negative 3, negative 2, positive 2 and positive 3, the answer is greater than 1.  

Out of seven integers given in the question, three of them have a square less than or equal to 1, to be specific these are -1, 0 and 1.  

Therefore, the probability of choosing a number where the square is less than or equal to one is 3/7.
