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: 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.
