Which are properties of a random variable? Select all that apply. Random variables are denoted with an upper case letter. Random variables are represented by numerical values.
The table below shows a probability density function for a discrete random variable X What is the probability that X is 2 . ?
The table below represents the probability density function for the random variable X Find the standard deviation of X Round the final answer to two decimal places. x P(X = x) 0 1/6 4 1/3 8 1/2 298 A softball pitcher has a 0.487 probability of throwing a strike for each pitch. If the softball pitcher throws 29 pitches, what is the probability that no more than 14 of them are strikes? P(X≤14) or P(X<15) Identify the parameter n in the following binomial distribution scenario. The probability of buying a movie ticket with a popcorn coupon is 0.657 and without a popcorn . .
coupon is 0.343 . If you buy 28 movie tickets, we want to know the probability that exactly 20 of the tickets have popcorn coupons. (Consider tickets with popcorn coupons as successes in the binomial distribution.)
The probability of winning on an arcade game is 0.568 . If you play the arcade game 22 times, what is the probability of winning more than 15 times?
The probability of buying a movie ticket with a popcorn coupon is 0.597 and without a popcorn coupon is 0.403 . If you buy 18 movie tickets, we want to know the probability that no more than 13 of the tickets have popcorn coupons. 18 A softball pitcher has a 0.721 probability of throwing a strike for each pitch and a 0.279 probability of throwing a ball. If the softball pitcher throws 19 pitches, we want to know the probability that more than 15 of them are strikes.
