For each random variable defined here, describe the set of possible values for the variable, and state whether the variable is discrete. (a) X = the number of unbroken eggs in a randomly chosen standard egg carton Describe the set of possible values for the variable. O 0, 1, 2, 3, ..., 12 O (0, 12] O 1, 2, 3,..., 12 O [0, 12] State whether the variable is discrete. O discrete O not discrete (b) Y = the number of students on a class list for a particular course who are absent on the first day of classes, where n = the total number of students on the class list Describe the set of possible values for the variable. O (0, n) O 0, 1, 2, 3,..., n 1, 2, 3,..., n O [0, n] State whether the variable is discrete. O discrete O not discrete (c) U the number of times a duffer has to swing at a golf ball before hitting it Describe the set of possible values for the variable. 1, 2, 3,... O 0, 1, 2, 3,... 0 (0,00) O [0,00) State whether the variable is discrete. O discrete Onot discrete (d) X = the length of a randomly selected rattlesnake Describe the set of possible values for the variable. O 0, 1, 2, 3,... O [0, 0⁰0) 0 (0,00) O 1, 2, 3, ... State whether the variable is discrete. O discrete O not discrete (e) Z = the sales tax percentage for a randomly selected amazon.com purchase, where n = the total number of possible sales tax percentages for online purchases Describe the set of possible values for the variable. O [0, n] OZ₁ Z₂ ZZn O [0, Z,] O 1, 2, 3, ..., n State whether the variable is discrete. O discrete O not discrete (f) Y = the pH of a randomly chosen soil sample Describe the set of possible values for the variable. O [0, 14] O (0, 14) 1, 2, 3,..., 14 O 0, 1, 2, 3,..., 14 State whether the variable is discrete. Odiscrete O not discrete

Give complete solution please

Which of the following numbers could be the probability of an event? 0.09, - 0.54, 1, 1.2, 0, 0.39 The numbers that could be a probability of an event are (Use a comma to separate answers as needed.)

A subset of a population selected to represent the population is a subset O sample small population None of the alternative answers is correct.

addition rule   cats and dogs       Among a group of 500 pet owners who visit the same pet store, it is found that 345 have a cat, while 375 have a dog. There are 290 of these who have both a dog and a cat.   Suppose one individual is chosen at random from this group of 500 pet owners.   a)  Find the probability the individual owns either a dog or a cat   b)  Find the probability the individual owns neither a dog nor a cat   c)  Find the probability the individual owns a dog but not a cat..
