Suppose $$W,X$$, and $$Y$$ follow binomial distributions with the number of trials and probability of success as indicated below. $$W$$ follows a binomial distribution with $$n_W=4$$ trials and probability of success $$p_W=0.2$$ $$X$$ follows a binomial distribution with $$n_X=6$$ trials and probability of success $$p_X=0.2$$ $$Y$$ follows a binomial distribution with $$n_Y=4$$ trials and probability of success $$p_Y=0.3$$ (If necessary, consult a list of formulas.) (a) Find $${?}_W,{?}_X$$, and $${?}_Y$$, the respective means of $$W,X$$, and $$Y$$. $$\begin{array}{l}{?}_W=\\ {?}_X=?\\ {?}_T=\end{array}$$ (b) The histograms of three binomial distributions are shown below. Match each of $$W,X$$, and $$Y$$ with the histogram of its distribution.
