The accompanying table describes results from groups of 8 births from 8 different sets of parents. The random variable x represents the number of girls among 8 children. Complete parts (a) through (d) below. E Click the icon to view the table, a. Find the probability of getting exactly 1 girl in 8 births. (Type an integer or a decimal. Do not round.) Probability distribution for x b. Find the probability of getting 1 or fewer girls in 8 births. Number of Girls x (Type an integer or a decimal. Do not round.) P(x) 0.002 0.019 0.119 c. Which probability is relevant for determining whether 1 is a significantly low number of girls in 8 births: the result from part (a) or part (b)? 1 O A. Since the probability of getting more than 1 girl is the complement of the result from part (b), this is the relevant probability. 3 0.189 O B. Since the probability of getting 1 girl is the result from part (a), this is the relevant probability. 0.342 5 0.189 OC. Since the probability of getting 0 girls is…
Determine whether the random variable x is discrete or continuous. Explain. Let x represent the distance a baseball travels in the air after being hit. Choose the correct answer below. O A. The random variable is discrete, because it has an uncountable number of possible outcomes. O B. The random variable is continuous, because it has an uncountable number of possible outcomes. O C. The random variable ks discrete, because it has a countable number of possible outcomes. D. The random variable is continuous, because it has a countable number of possible outcomes.

Recal the example in class and also in the notes I sent to you. Work again on the example as follows. Example: Suppose that 2 defective microwaves have been included in a shipment of 6 microwaves. The buyers want to test the 6 microwaves one at a time. Let Y denote the number of defective microwaves is found after 3 random selected ones have been tested. Find the probability distribution for Y. Y = the number of defective microwaves found after 3 have been tested What's the possible value of Y? Y P(Y=y) ? ? Questions: 1- Fill the table above with random variables and corresponding probabilities? 2- Calculate the probability that the buyers can find at least 1 defective microwave after 3 have been tested? 3- Find the probability that buyers cannot find any defective microwave after 3 random ones have been tested?
