Question

Event A 12 green 5 blue and 7 black marbles Event B a spinner with a red blue and green section what will be the odds against drawing a green marble and landing on red please add your answer A 1/4 B 2/10 C 1/6 D 1/8

Answer 1

prob(green marble) = 12/24 = 1/2
prob(landing on red) = 1/3

prob(green marble AND landing on red) = (1/2)(1/3) = 1/6 , .... they are independent event
prob(against the above stated event) = 5/6

odds against stated event
= prob(against the event) : prob( of the event)
= 5/6 : 1/6
= 5 : 1
