Guys, I got this task that I couldn't solve. I will be very grateful for the detailed explanation.
Random variable x represents the number of girls in a family of four children.
1) Construct a table describing the probability distribution, then find the mean and standard deviation. (Hint: List the different possible outcomes.)
2) Is it unusual for a family of four children to consist of four girls?
I will be incredibly grateful for your help with the decision.
