Consider a family with four children. A survey indicates that it is reasonable to believe that the probabilities of having 0, 1, 2, 3, or 4 sons in such a family are, respectively, 0.1, 0.2, 0.35, 0.2, and 0.15. Find the probability that in a family with four children there will be: (a) (2 marks) at least two sons; 3 (b) (2 marks) at most two sons.

A recent survey by the New Statesman on British social attitudes asked respondents if they believe that inequality is too large. The survey found that 83% of the respondents do believe inequality is too large. In a sample of six British citizens, what is the probability that two believe inequality is too large? If required, round your answer to four decimal places. f (2) = In a sample of six British citizens, what is the probability that at least two...

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...
