Urn i contains three red chips and five white chips; urn ii contains four red sand four whites; urn iii contains five red sand three whites. one urn is chosen at random and one chip is drawn from that urn. given that the chip drawn was red, what is theprobability that iii was the urn sampled?

0.416

Step-by-step explanation:

This problem is solve by using Baye's Probability.

Let P(U1) = Probability that Urn I is selected = 1÷3

P(U2) = Probability that Urn II is selected = 1÷3

P(U3) = Probability that Urn III is selected = 1÷3

Alos Let, R = Red ball is chosen

and W = White ball is chosen

Then, P(R/U1) = 3÷8

P(W/U1) = 5÷8

P(R/U2) = 4÷8

P(W/U2) = 4÷8

and, P(R/U3) = 5÷8

P(W/U3) = 3÷8

Then by Baye's Theorem,

⇒  

⇒ P(U3| R) = 0.416

which is required probability.

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.

answer: the answer is ann
