I have attached 7 homework questions dealing with probability and Counting for my computer science class(discrete math) here are the problems below: I have 7 problems that I need help on ASAP!!! COULD YOU PLEASE HELP.. These problems deal with Counting and Probability 1. A box contains 24 light Bulbs. The quality control engineer will pick a sample of 4 bulbs for inspection. Suppose that there are 4 defective light bulbs in the box a. What is the probability that the sample will contain all 4 defective bulbs? b. What is the probability that the sample will contain no defective bulbs? 2.A student is guessing on his 20-question multiple-choice test. If each question has five choices, what is the probability he will answer at least 15 questions correctly?(The hint given: this is a Bernoulli problem. What is the probability p of success for one question?) 3. On one biased dice, the probability of an odd number showing is twice the probability of an even number showing. Find the probability of each outcome of rolling on of the biased dice.
