A group of instructors have decided to assign grades on a curve. Random variable : a numerical characteristic that takes on different values due to chance Coin Flips The number of heads in four flips of a coin a numerical property of each different sequence of flips is a random variable because the results will vary between trials. A continuous random variable has an infinite number of possible values so we can't assign probabilities to each specific value. Example Red Flowers, cont. Need an extra hand?
