**Question:** Given this table, find the probability of \( x \) less than or equal to 1. | x | 0 | 1 | 2 | |---|----|----|----| | P(x) | 0.50 | 0.25 | 0.25 | **Options:** - ☐ 0.75 - ☐ 0.25 - ☐ 1 - ☐ 0.50 **Explanation:** To find the probability \( P(x \leq 1) \), sum the probabilities for \( x = 0 \) and \( x = 1 \): \[ P(x \leq 1) = P(x = 0) + P(x = 1) \] \[ P(x \leq 1) = 0.50 + 0.25 \] \[ P(x \leq 1) = 0.75 \] Thus, the correct answer is 0.75.
