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.

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. Click the icon to view the table. a. Find the probability of getting exactly 6 girls in 8 births. (Type an integer or a decimal. Do not round.) b. Find the probability of getting 6 or more girls in 8 births. (Type an integer or a decimal. Do not round.) c. Which probability is relevant for determining whether 6 is a significantly high number of girls in 8 births: the result from part (a) or part (b)? A. The result from part a, since it is the exact probability being asked. B. The result from part b, since it is the probability of the given or more extreme result. C. The result from part a, since it less than the probability of the given or more extreme result. D. The result from part b, since it is the complement of the result of part a. d. Is 6 a significantly high number of girls…
