Probability Question

Question

A carnival roulette wheel contains 26 slots numbered 00,0,1,2,3,...,24. 12 of the slots numbered 1 through 24 are colored red, and 12 are colored black. The 00 and 0 slots are uncolored. The wheel is spun, and a ball is rolled around the rim until it falls into a slot. What is the probability that the ball falls into a black slot?

Answer 1

desired outcome = black slot = 12 choices

total outcomes = black, red, and uncolored = 26 choices

 

probability of black = desired/ total = 12/26 = 6/13
