K The data on the right represent the number of live multiple-delivery births (three or more babies) in a particular year for women 15 to 54 years old. Use the data to complete parts (a) through (d) below. Age 15-19 20-24 25-29 30-34 35-39 40-44 45-54 Number of Multiple Births (a) Determine the probability that a randomly selected multiple birth for women 15-54 years old involved a mother 30 to 39 years old. P(30 to 39)= (Type an integer or decimal rounded to three decimal places as needed.)

Condom Failure Rate: According to the Department of Health and Human Services, the failure rate for male condoms is 18%. The accompanying table is based on the failure rate of 18%, where x represents the number of condoms that fail when six are tested. x P(x) 0 0.304 1 0.400 2 0.220 3 0.064 4 0.011 5 0.001 6 0+ Does the table describe a probability distribution? Why or Why not? Assuming that the table does describe a probability distribution, find its mean? Assuming that the table does describe a probability distribution, find its standard deviation? If 6 condoms are tested and 5 of them fail, is 5 a significantly high number of failures? Why or Why not? What does the symbol 0+ represent?
High school students in Michigan sometimes get "snow days" in the winter when the roads are so bad that school is canceled for the day. Define the random variableX = the number of snow days at a certain high school in Michigan for a randomly selected school year. Suppose the table below gives the probability distribution of X. 1. Value x, 1. 3 4 5 6 7 8 9 10 Probability p, ? 0.19 0.14 0.10 0.07 0.05 0.04 0.04 0.02 0.01 0.01 (a) Write the event “the school year has O snow days" in terms of X. Then find its probability. (b) At this high school, if more than 5 snow days are used over the course of the year, students are required to make up the time at the end of the school year. What's the probability that a randomly selected school year will require make-up days?

Dragon Dice is a tabletop game that uses modified dice to roll for the values 1, 2, 3 and 4 (note that the die is not fair). Let the random variable D represent the value of a single roll of the die. The table below represents the probability distribution for the random variable D. Determine the missing value so that the probability distribution is valid. x P(D=x) 1 2 0.26 3 0.34 4 0.28 True or False: The random variable D is a continuous random variable. Compute the probability that at most a 2 is rolled on a single roll of the die. On your turn, you attempt to capture a Giggling Goblin with a stomp attack using two dice. To capture the Giggling Goblin, you must roll a total of at least 5. On the first die roll you roll a 1. Choose the most correct statement concerning your chances of capturing a Giggling Goblin on this turn. Group of answer choices a. There is no way to capture a Giggling Goblin since P(D≥5)=0. b. There is a 28% chance to capture a Giggling…
