Two Basic Rules of Probability · Exercise 15

A local restaurant sells pork chops and chicken breasts. The given values below are the weights (in ounces) of pork chops and chicken breasts listed on the menu. Your server will randomly select one piece of meat (pork chop or chicken breast) that you will be served.
$$\begin{array}{ccccccccccc}\text{Pork Chops}& \text{17}& \text{20}& \text{21}& \text{18}& \text{20}& \text{20}& \text{20}& \text{18}& \text{19}& \text{19}\\ \text{20}& \text{19}& \text{21}& \text{20}& \text{18}& \text{20}& \text{20}& \text{19}& \text{18}& \text{19}& \\ \text{Chicken Breasts}& \text{17}& \text{19}& \text{17}& \text{21}& \text{17}& \text{21}& \text{18}& \text{21}& \text{19}& \text{21}\\ \text{20}& \text{17}& \text{20}& \text{18}& \text{19}& \text{20}& \text{20}& \text{17}& \text{21}& \text{20}& \end{array}$$

Compute the probabilities:

(a) P(you will not get a pork chop)
(b) P(you will get a 20-oz. pork chop)
(c) P(you will not get a chicken breast or you will not get an 18-oz. pork chop)
(d) P(you will not get a chicken breast and you will not get an 18-oz. pork chop)
(e) P(you will get a pork chop that is not 21 oz.)
(f) P(you will not get a chicken breast or you will not get a pork chop)
