Answer

\( P(X<24)=0.75 \) \( P(X \geq 24)=0.25 \) \( P(19.5 \leq X \leq 24.0)=0.5625 \) \( P(X=22.22)=0 \)

Solution

For X ~ U(18,26): 1. P(X < 24) = (24 - 18) / (26 - 18) = 6/8 = 0.75 2. P(X ≥ 24) = (26 - 24) / (26 - 18) = 2/8 = 0.25 3. P(19.5 ≤ X ≤ 24.0) = (24.0 - 19.5) / (26 - 18) = 4.5/8 = 0.5625 4. P(X = 22.22) = 0 (since the probability of any single point for a continuous distribution is 0)

Bonus Knowledge

For a uniform random variable \( X \sim U(18,26) \), we know that the probability density function is constant within the bounds of the distribution. First, let's calculate each required probability: 1. To find \( P(X < 24) \): \[ P(X < 24) = \frac{24 - 18}{26 - 18} = \frac{6}{8} = 0.75 \] 2. For \( P(X \geq 24) \): \[ P(X \geq 24) = 1 - P(X < 24) = 1 - 0.75 = 0.25 \] 3. To calculate \( P(19.5 \leq X \leq 24.0) \): \[ P(19.5 \leq X \leq 24.0) = \frac{24 - 19.5}{26 - 18} = \frac{4.5}{8} = 0.5625 \] 4. Since \( X \) is continuous, \( P(X = 22.22) = 0 \). Putting it all together: - \( P(X < 24) = 0.75 \) - \( P(X \geq 24) = 0.25 \) - \( P(19.5 \leq X \leq 24.0) = 0.5625 \) - \( P(X = 22.22) = 0 \)
