6. Your friend is playing roulette at the same casino with you, but she decides to play 10 times and then leave. 1. What's the probability that she loses 4 games? This means she wins 6. 2. What's the probability that she wins more games than she loses?
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!
For the following question, state and explain what the most reasonable distribution is to model the problem, define a random variable, and use that distribution to calculate the probabilities. Show your calculations, and express the
