What is Permutation and Combination ?
A permutation is an act of arranging the objects or numbers in order. Combinations are the way of selecting the objects or numbers from a group of objects or collection, in such a way that the order of the objects does not matter.
A bag contains one green ball, one yellow ball, one red ball, and one blue ball.
Jerome picks a ball from the bag, replaces it, and then picks another ball.
Order matters since the ball is being replaced each time.
This is all the possible combinations to take 2 balls with replacement,
GY YY RY BY GR YR RR BR GB YB RB BB GG YG RG BG
For the first missing blank , RR, RB, and RG are listed and the only other combination when choosing a red first would be to pick a yellow, so RY.
This is the same pattern for the others also.
