A car manufacturer produces only red and blue models which come out of the final testing area completely at random. What are the odds that 5 consecutive cars of the same color will come through the test area at any one time?
a)1 in 16
b)1 in 125
c)1 in 32
d)1 in 25

• p(5 cars of same color)= p(5 red cars) + p(5 blue cars)
  hence p(5 cars of same color) = (1/2)^5 + (1/2)^5
  ans = 1/16

• c) 1/2*1/2*1/2*1/2*1/2=1/32

• c)1 in 32
  1/2*1/2*1/2*1/2*1/2
  =(1/2)^5=1/32

• (1/2)^5=1/32

• Selecting of red color car or blue color car at random is 1/2. Therefore probability of 5 consecutive car of the same color come through test at the same time is 1/2*1/2*1/2*1/2*1/2=1/32
