A toy train produces 10 different tunes when it moves around a circular track of radius 5 meters, at 10 meters per minute.However the toy train is defective and it now produces only two different tunes at random. What is the probability that the toy train produces 6 consecutive music of the same type (1 in ----)? 64, 6, 36, 32

• probablity for the first sound to occur 6 times consecutively=1/(2^6)
  probablity for the second sound to occur 6 times consecutively=1/(2^6)
  total probab=(1/(2^6))+(1/(2^6))=1/32
  hence 32 is the answer
