A collector has 16 bottles. 5 identical blue bottles, 5 identical green bottles and 6 identical purple bottles.
a. How many different ways can he present by putting the 16 bottles in a line?
b. What if he wants to put 5 of the bottles into a bag. How many different(not ordered) bags are possible?
a) here total 16 bottles
So 16 bottles can arrange in 16! ways in a line
So 16! = 20922789888000 way can arrange 16 bottles in a line
b) If he wants to put 5 of the bottles into a bag.
So group of any 5 in a bag order not matter so we need to use combintion of 5 bottles out of 16 bottles
20922789888000 20922789888000
= --------------------------------- = ------------------------ = 4368
120* 39916800 4790016000
So there are 4368 different ways bags are possible with 5 bottles ina bag.\
Hope this will help you.
Thank you.
