A and B stand in a circle with 14 other persons.if the arrangement is random,what is the chance that there are exactly 4 persons between A and B.

• 22 possible ways bcoz totally 16 members...if A is in pos 1 then B will b in pos 6..then ll be in pos 2 and 7 and goes on upto 16 and 5..so 11*2(position change)=22...

• 4 people should be placed between A and B so 14P4=14!/10!=14*13*12*11= 24024
