The following probability model shows the distribution of the most-popular-selling Girl Scout Cookies ® .

 Cookie Type Probability Thin Mints 0.27 Samoas/Caramel deLites 0.21 Peanut Butter Patties/Tagalongs 0.17 Peanut Butter Sandwiches/ Do-is-dos 0.15 Shortbread/Trefoils 0.12 Other varieties 0.08

(a) Verify that this is a probability model. If a girl scout is selling cookies to people who randomly enter a shopping mall, what is the probability that the next box sold will be Peanut Butter Patties ® / Tagalongs™ or Peanut Butter Sandwich/Do-si-dos™?

(b) If a girl scout is selling cookies to people who randomly enter a shopping mall, what is the probability that the next box sold will be Thin Mints, Samoas ® /Caramel deLites™, or Shortbread/Trefoils?

(c) What is the probability that the next box sold will not be Thin Mints?
