Accepted Solution

A:
Answer:Option A: P(Male or Type B) > P(Male | Type B) Step-by-step explanation:Total Female = 85 type A, 12 type B  ⇒ 97 Female.Total Male = 65 type A, 38 type B   ⇒ 103 MaleTotal type A = 65 + 85 = 150Total type B = 12 + 38 = 50total number of people = 97 + 103 = 200Then the probability would be:P(Male | Type B) = [tex]\frac{number of male in B}{total number of male}[/tex]                            = [tex]\frac{38}{103}[/tex]                            = 0.368P(Male or Type B) = [tex]\frac{total number of male + (total number of people in B - total number of male in B)}{total number of male}[/tex]                               =  [tex]\frac{103 + (50 - 38)}{200}[/tex]                               = [tex]\frac{103 + 12}{200}[/tex]                               = [tex]\frac{115}{200}[/tex]                               = 0.575 Hence, P(Male or Type B) > P(Male | Type B)
