Explain why x is or is not a binomial random variable. (HINT: Compare the characteristics of this experiment with those of a binomial experiment given in this section.) Two balls are randomly selected without replacement from a jar that contains six red and four white balls. The number x of red balls is recorded. O The random variable x is not a binomial random variable since there is an unequal number of red and white balls in the jar. For this reason, the probability p of choosing a red ball changes from trial to trial. O The random variable x is not a binomial random variable since the balls are selected without replacement. For this reason, the probability p of choosing a red ball changes from trial to trial. O The random variable x is a binomial random variable since the balls are selected without replacement. For this reason, the probability p of choosing a red ball does not change from trial to trial. O The random variable x is a binomial random variable since there is an unequal number of red and white balls in the jar. For this reason, the probability p of choosing a red ball does not change from trial to trial. If the experiment is binomial, give the values of n and p. (If the experiment is not binomial enter NONE.) P =
