jar 1: 600 red and 400 white
jar 2: 900 blue and 100 white
jar 3: 10 green and 990 white
If you blindly select one marble from each jar, calculate the probability of obtaining only whites. 0.9946 0.4162 0.0006 0.0054 0.0396
Explanation / Answer
45 A PART 2)
jar 1: p(w)=400/(600+400)=0.4
jar 2:p(w)=100/(900+100)=0.1
jar 3:p(w)=990/(10+990)=0.99
therefore, probability of all whites =0.4x 0.1x 0.99=0.0369
45 A part 3)since red and green comes from 1st and 3rd jar respectively, white comes from 2nd jar
p(red)=600/(600+400)=0.6
p(green)=10/(10+990)=0.01
p(white)=100/(900+100)=0.1
p(R,G,W)=0.6X 0.01X 0.1=0.0006
45A part 5)a colour and two whites are as follows:
summing up; 0.0594+0.3564+0.0004=0.4162
45a part 6) atleast one white =1- probability of no whites
i.e= 1- p( other colours)
=1-p(red, blue, green)
= 1-(0.6x 0.9 x 0.01)
=1- 0.0054
=0.9946
45c)probability of success is 20%
hence probability of failure is 80%
i.e 0.8 for each egg so for 5 eggs, it is (0.8) 5
probability of success of atleast one egg =1-0.328=0.627
