2. A car manufacturer produces only red and blue models which come out of the final testing area at random. What are the odds that five consecutive cars of 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

• a) 1 in 16
  First car can come out with any colour with prob 1.
  second car will come out with probability of same color as 1/2.
  third car will come out with probability of same color as 1/2.
  4th car will come out with probability of same color as 1/2.
  5th car will come out with probability of same color as 1/2.
  
  so odds are 1*1/2* 1/2* 1/2 *1/2=1/16

• FOR COLOR RED-->(1/2)^5=1/32
  FOR BLUE-->1/32
  SO PROBABILITY=1/32+1/32=1/16

• 1 in 32 is the answer
  probability of 1 car among blue and red is 1/2
  and if it chooses 5 times the answer will be
  
  1/2*1/2*1/2*1/2*1/2=1/32

• P(red car/blue car)= 1/2; P(all 5 red cars or blue will be chosen)=1/(2^5)=1/32;

• 1 in 32 is the answer
  probability of 1 car among blue and red is 1/2
  and if it chooses 5 times the answer will be
  
  1/2*1/2*1/2*1/2*1/2=1/32
