Adeck of cards contains red cards numbered 1,2,3 and blue cards numbered 1,2,3,4,5,6. let r be the event of drawing a red card, b the event of drawing a blue card, e the event of drawing an even numbered card, and o the event of drawing an odd card. drawing the blue 4 is an example of which of the following events? select all correct answers. select all that apply: a. r or ob. b and oc. r or ed. r and oe. r′f. e′

E

Step-by-step explanation:

Red cards = 1,2,3

Blue cards =1,2,3,4,5,6

Pr(R) =  Drawing a red card = 3/9 = 1/3

Pr(B)= Drawing a blue card = 6/9 = 2/3

Pr(E) = Drawing an even card = 4/9

Pr(O) = Drawing an odd number card = 5/9

Probability of drawing the blue 4 ? = Pr(blue, 4) = 1/9

From the options

(A) R or O = Pr(R) + Pr(O)  = 1/3 + 1/9 = 8/9 (Not equal to 1/9)

(B) B and O = Pr(B) × Pr(O) =  2/3 × 5/9 = 10/21(Not equal to 1/9)

(C) R or E = Pr(R) + Pr(E) = 1/3 + 4/9 = 7/9(Not equal to 1/9)

(D) R and O = Pr(R) + Pr(O) = 1/3 × 5/9 = 5/27(Not equal to 1/9)

(E) R'. E' = 1-Pr(R)-1-Pr(E) =

                 1-1/3 =2/3- 1-4/9 =5/9

                2/3-5/9 = 1/9( equal to 1/9).
