Document Summary
Math1070q notes- lecture #12- random variables and histograms. X is the number of times we get heads. Since there is a finite # of outcomes. This is a finite discrete random variable. A value that is at least 10. This is a infinite discrete random variable. X is the amount of time it takes for your friend to catch his first fish. Since we are dealing with time, any number greater than 0. # of times a die is rolled until you roll a 3. Amount of time spent studying for a class each week. # of cards pulled until a queen of spades in pulled, cards are replaced. Frequency/ # of total times = probability of successes. X= number of times we get tails. P= 0. 5, q= 0. 5, n = 5, k = 0, 1, 2, 3, 4, 5. Can plug this data into a histogram. Probability on y axis, x on x axis.
