A mom walks into her child's room and finds clothes all over the floor. 20% of the clothes are clean. She randomly picks up 5 articles of clothing. 1. We can expect out of articles of clothing to be clean. 2. The standard deviation is (Round to the nearest tenth, if necessary.) 3. Because the distribution has a probability of success (P(S)) that is the distribution is close to 4. Use the probability formula P(r) =, C,p' q"- to create a binomial distribution table. Probability formula Round to the tenth, if necessary. P(r) Enter the probability only. Round to the 4th decimal place, if necessary. 1 2 C 3 4 5 Check
Continuous Probability Distributions
Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.
Normal Distribution
Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!
