Solution

The probability for the question will be 1/16 and answer of AMAR is right but question is saying about odds and odds mean favorable probability/non favorable probability = (1/16)/(15/16) = 1/15
odds has two category 1) in favour 2) against
odds in favour = favorable probability/non favorable probability
odds against = non favorable probability/ favorable probability

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

Is this solution Helpfull? Yes (3) | No (4)
