Urn 2 contains 4 red balls and 1 black ball. Urn 3 contains 6 red balls and 4 black balls. If an urn is selected at random and a ball is drawn, find the probability that it will be red. Enter your answer as a fraction or a decimal rounded to 3 decimal places P(red)-

Explanation / Answer

Ans:

P(red/Urn 1)=5/6

P(red/Urn 2)=4/5

P(red/Urn 3)=6/10

P(urn 1)=P(urn 2)=P(urn 3)=1/3

P(red)=(5/6)*(1/3)+(4/5)*(1/3)+(6/10)*(1/3)=(1/3)*[0.833+0.8+0.6]=2.233/3=0.744
