Egyptian Let x represent the number of children in an Egyptian household.The probability distribution of x is as follows: \[\begin{array} { l | c c c c c } x & 1 & 2 & 3 & 4 & 5 \\ \hline p ( x ) & 0.25 & 0.33 & 0.17 & 0.15 & 0.10 \end{array}\] -What is the probability that a randomly selected Egyptian household will have fewer than 4 children?

The answer of Egyptian Let x represent the number of children...

Exam 6: Discrete Probability Distributions

Canoe club A canoe club sponsor has taken canoeing groups through a particularly rough section of white water on a mountain river.Past trips and experience of the sponsor lead her to believe that fifty percent of the canoeists who attempt to paddle their way through this section will overturn.At the present time,there are five canoes approaching this treacherous section.Assume that the sponsor's estimate of the probability of a canoe overturning in this section of water is accurate. Develop the probability distribution of the number of canoes that will capsize.
