40 treasure chest of type a and 60 treasure chest of type B each treasure chest of type a holds 30 gold coins and 70 silver coins and each treasure chest of type B holds 20 gold and 80 silver coins choose a treasure chest uniformly at random and pick a coin from that chest uniformly at random if the coin is gold, then what is the probability that you chose a chest of type a
Added by Lourdes C.
Step 1
Total number of gold coins = (40 treasure chests of type A) * (30 gold coins per chest) + (60 treasure chests of type B) * (20 gold coins per chest) Total number of gold coins = 1200 + 1200 Total number of gold coins = 2400 Show more…

Bayes Theorem, P(B|A) = P(A|B)P(B) / (P(A|B)P(B) + P(A|B̅)P(B̅)) Suppose you are going treasure hunting. The probability of finding gold given that you have found a pirate's chest is 0.95. The probability of finding a pirate's chest is 0.0001. Finally, the probability of finding gold in a chest that is not a pirate's chest is 0.01. What is the probability that you will find a pirate's chest given that it's full of gold?

Suppose you have three urns in front of you that look the same but are of different types: The A-type urn holds 30 yellow balls, 60 green balls, and 10 red balls. The B-type urn holds 10 yellow balls, 80 green balls, and 10 red balls. The C-type urn holds 50 yellow balls, 10 green balls, and 40 red balls. If you randomly select one of the urns, what is the probability of picking the A-type urn? (Hint: Requires no calculation)

A box contains 3 gold coins, 4 silver coins, and 5 bronze coins. Two coins are drawn at random without replacement. What is the probability that the first coin is gold and the second coin is silver, given that no bronze coins were drawn?
