Question

do part d,e,f, and g

There are 261 marbles in a jar. The marbles are either colored Red, Green, or Blue, and they are made from either Glass, Steel, or Plastic. The table gives information on the marbles: Glass Steel Plastic Total Red 18 30 79127 Green80 6 13 99 Blue 10 5 2035 Total 108 41 112 261 For example, 79 marbles are Red and made of Plastic. The table also gives totals for each category. For example, 127 marbles are Red, while 108 marbles are made of Glass. Suppose a marble is drawn at random. a) What is the probability that marble is Blue and made of Glass? 10/261 b) What is the probability that marble is Blue? 35/261 c) What is the probability that marble is made of Glass? 108/261

Explanation / Answer

(d) Pr(Blue l Glass) = Total number of blue marble which are glass too/ Total number of glass marble = 10/ 108

(e) Pr(Glass l Blue) = Total number of glass marble which are blue too / Total number of blue marble = 10/35 = 2/7

(f) Pr (Red l Glass) = Total number of Red marble which are glass too/ Total number of Glass marble = 18/108 = 1/6

(g) Pr(Glass l Red) = Total number of Glass marble which are red too / Total number of Red marble = 18/127
