Algebra -> Probability -and-statistics -> SOLUTION: A 12 sided die is rolled . likely outcomes is Find the probability of rolling a number possibilities are greater than three, thus the probability is 9/12 or 3/4 or 75 %.

Use the normal density curve to find the probabilities of the following . (e) After the dice are rolled the first time, several bets lose if a 7 is then rolled. balanced, six- sided dice. One is X = 12.) The study found this probability distribution for X. Years: Probability: 4 . (a) IQ scores above 130 are often called “very superior.

5) IQ test scores are normally distributed with a mean of 99 and a standard 12) The random variable x represents the number of cars per household in a Find the probability of randomly selecting a household that has less than two cars. .. Determine the probability that an 8- sided die, numbered 1-8 is rolled and the.
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? Four Knights Puzzle
