Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A factory produces light bulbs, with a 5% chance of each bulb being defective. If you randomly select 10 bulbs, model the number of defective bulbs as a binomial distribution. What is the expected number of defective bulbs?

💡 Hint: Consider the probability of defectiveness for each bulb.

Challenge 2 Hard

A car's speed is modeled as a continuous random variable with PDF f(x) = kx for 0 ≤ x ≤ 2. Determine k and then find the CDF.

💡 Hint: Use integration to derive the total area under the PDF.
