Chapter 8.1, Problem 88E

In Problems $87\text{-}90$, several experiments are simulated using the random number feature on a graphing calculator. For example, the roll of a fair die can be simulated by selecting a random integer from, and $50$ rolls of a fair die by selecting $50$ random integers from $1\text{ to }6$ (see Fig. A for Problem $87$ and your user's manual).

Use a graphing calculator to simulate $200$ tosses of a nickel and dime, representing the outcomes $\text{HH,}\text{HT,}\text{TH,}\text{TT}\text{by}\text{1,}\text{2,}\text{3,}\text{and}\text{4}$, respectively.

(A) Find the empirical probabilities of the four outcomes.

(B) What is the probability of each outcome under the equally likely assumption?
