Answer» Favourable outcomes are -1, 0, 1 Required probability = 3/7 Detailed Answer: S = {-3, -2, -1, 0, 1.,2,3} Let E be the event of getting a number whose square is less than or equal to 1. So, E = {-1,1,0) P(E) = 3/7 Hence, the probability of getting a number whose square is less than or equal to 1 is 3/7. |
