A toy train produces 10 different sounds when it moves arrond a circular toy track of radius 5m at 10m per min. however, the toy train is defective and it now produces only 2 different sound at random. what are the odds that the train produces for consecutive music tones of the same type?

• now the train produces 2 sounds let it be Sound A and Sound B
  p=either train produces Sound A four times or it is Sound B
  probabilty that train makes sound A consecutively two times is 1/2*1/2
  similarly train makes Sound B consecutively two times 1/2*1/2
  so p=1/4 + 1/4 =1/2

• 
  there are 4 slots probability of both tunes of same type.
  1/2*1/2*1/2*1/2+1/2*1/2*1/2*1/2=1/8

• the toy train first produce two different sounds....then with respect of this the probability for consecutive music tones of same type is (1/2)^5
