Can someone please help me complete this question. Any help would be very much appreciated. Thank you. Let x determine a random variable, and use your knowledge of probability to prepare a probability distribution A family has four children and the number of girls is recorded. (Assume an equal chance of a boy or girl for each birth.) Complete the probability distribution. P(x) 16 Type an integer or a simplified fraction.)

For the experiment described below, let x determine a random variable, and use your knowledge of probability to prepare a probability distribution. Four cards are drawn (with replacement) and the number of black cards is noted. A probability distribution for the given experiment is as follows. х 0 1 2 3 4 1 16 P(x) 16 4 8
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 0.31. The table on the right describes the probability of 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 three girls? 0 1 2 3 P(x) 0.329 0.443 0.199...

Among 450 randomly selected drivers in the 20-24 age bracket, 9 were in a car crash in the last year. If a driver in that age bracket is randomly selected, what is the approximate probability that he or she will be in a car crash during the next year? Is it unlikely for a driver in that age bracket to be involved in a car crash during a year? Is the resulting value high enough to be of concern to...
In the following probability distribution, the random variable x represents the number of activities a parent of a 6 th- to 8th-grade student is involved in.
