distributions and Bl P(x) Let the random variable x represent the number of girls in a family with three children. Assume the probability of a child being a girl is 0.37. The table on the right describes the probability of 0.250 having x number of girls. Determine whether the table describes a probability distribution. If it does, find the mean and standard deviation. Is it unusual for a family of three children to consist of 0.441 W N - O three girls? 0.259 0.050 Find the mean of the random variable. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A H= (Round to two decimal places as needed.) O B. The table is not a probability distribution.
