Cooking oil is produced in two main varieties mono and polyu

Cooking oil is produced in two main varieties: mono- and polyunsaturated. Two common sources of cooking oil are corn and canola. The following table shows the number of bottles of these oils at a supermarket: Round your answers to four decimal places If a bottles of oil is selected at random, what is the probability that it belongs to the polyunsaturated category? What is the probability that the chosen bottle is monounsaturated canola oil?

Solution

a.

P( PoluUnsaturated) = n(Poly)/n(Total) = 166/186 = 0.8924
b.

P(MonoCannola) = N(Mona And Cannola)/ n(Total) = 9/186 = 0.0483

	Cannola	Corn
Mono	9	11	20	A1
Poly	91	75	166	A2
Totals	100	86	186
