Question

2. 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:

The number selected must be -1, 0, or 1 so that its square is <= 1. Out of seven numbers, three belong to the our favorable set. Since the number is randomly selected, the probability of picking any number is same. Hence, the probability (in this case) would be 3/7 or about 43%.
