Below are sample questions representative of the exercises included on this worksheet and related 5.169 Calculate Simple Probabilities and Complementary Probabilities skill assessments:

Problem 1Difficulty: Mastery

Delivery Timing: A delivery arrives on time with probability 0.85. Assume three deliveries are independent. What is the probability NOT all three deliveries are on time? (Round to the nearest thousandth.)

Solution & Explanation:First find P(all three on time) by multiplying 0.85 × 0.85 × 0.85 = 0.614125. The question asks for NOT all on time, so take 1 − 0.614125 ≈ 0.386.

Problem 2Difficulty: Mastery

Solve Using the Complement Rule: If P(not A) = 0.091, what is P(A)?

A0.091

B0.909

C1.091

D0.500

Solution & Explanation:P(A) = 1 − P(not A) = 1 − 0.091 = 0.909.

Problem 3Difficulty: Mastery

Attendance Over Time: A student is absent on a day with probability 0.04 (assume days are independent). Over 10 days, what is the probability the student is absent at least once? (Round to the nearest thousandth.)

Solution & Explanation:At least one absence = 1 − P(no absences). No absence on a day is 0.96, so multiply 0.96 by itself 10 times, then subtract from 1.
