i need correct answer

Question T [1 mark] Let A = {a,b,c} and B={1,2,3,4}. Choose a function fIArB uniformly at random (from the set of all such functions). What is the probability that f is injective? Enter your answer to three d.p_s (an answer within 10.001 will be considered correct) Enter number Question 8 [1 mark] Suppose we have three urns with black and white balls distributed as follows: :- Urn A has 1t] black balls and 20 white balls 0 Urn B has 10 black balls and 10 white balls 0 Urn C has 10 black balls and 1 white bail. Suppose we choose an urn (uniformly at random) and draw a ball (uniformly at random) from that urn. 1il'll'hat is the probability that the ball is white? (a) O 33:19:; (b) O 31 :61 (c) 0 4m (d) O was
