Please help me answer question 3 & 4

would best be modeled as continuous or discrete: The tenp beverage vending machine, taken four times during a 24-hour period. Continuous b. Diserete Use the following information to answer questions (3)-(4), A package delivery service divides their packages into weight classes. Suppose that the packages in the 14-20 pound class are uniformly distributed, meaning that all weights within that class are equally likely to occur. The probability density curve is shown below Density 0.2 0.0 14 20 Weight [Objective: Understand the uniform probability distribution] Find the probability that a package weighs less than 20 pounds? 3. a. 0.80 b. 0.40 c. 1.00 d. 0.20 4. [Objective: Understand the uniform probability distribution) Find the probability that a package weighs between 14 and 18 pounds? a. 0.67 b. 0.33 0.40 d. 0.80

Explanation / Answer

3. P(Package weighs less than 20 pounds)

= (20 - 14)/(20 - 14)

= 6/6

= 1

Option C is correct.

4. P(Package weighs between 14 and 18 pounds)

= (18 - 14) / (20 - 14)

= 4/6

= 0.67

Option A is correct.
