No square can be negative.
So the only numbers whose squares are less than or equal to 1, - 1, 0 and 1.
So favorable outcomes = 3
Total outcomes = 7
P(E) = 3/7

Total number of Outcomes = 7
Favourable Outcomes are - 1, 0 and 1
Number of Favourable Outcomes = 3
Probability of given condition = Favourable Outcomes / number of Outcomes
= 3 /7
Favourable Outcomes are - 1, 0 and 1
Number of Favourable Outcomes = 3
Probability of given condition = Favourable Outcomes / number of Outcomes
= 3 /7
Sorry lemme answer
