$$P(4 \le \text{wait time} \le 7) = ~~ ?$$

$$P(4 \le \text{wait time} \le 7) = ~~ ?$$

$$P(4 \le \text{wait time} \le 7) = 3 \times 1/12 = 3/12$$

$$ P(\text{wait time} \le 7) = ~~ ?$$
$$ P(\text tempo de espera) \le 7) = \frac{7-0}{12} $$
$$ P(\text tempo de espera \le 7) = \frac{7}{12} = 58,33% $$

$$P(0 \le \text{wait time} \le 12) = ~~ ?$$

$$P(0 \le \text{outcome} \le 12) = 12 \times 1/12 = 1$$

$$ P(\text tempo de espera \ge 7) = 1 - \frac{7}{12} $$
$$ P(\text tempo de espera \ge 7) = \frac{5}{12} = 41,67% $$
