Algebra.Com's Answer #453731 by sachi(548) You can put this solution on YOUR website! There are 4 hotels in a certain city. If 3 men check into hotels in a day, \n" ); document.write( "the probability that each check into (i) a different hotel \n" ); document.write( "the 1st man enters into a hotel 1n 4 ways \n" ); document.write( "the 2nd man enters into a hotel 1n 3 ways (as one hotel is booked ) \n" ); document.write( "the 3rd man enters into a hotel 1n 2 ways (as two hotel is booked ) \n" ); document.write( "so the probability =4*3*2=24 \n" ); document.write( "the probability that each check into (ii) the same hotel. \n" ); document.write( "the 1st man enters into a hotel 1n 4 ways \n" ); document.write( "the 2nd man enters into a hotel 1n 4 ways (as hotel is repeated ) \n" ); document.write( "the 3rd man enters into a hotel 1n 4 ways (as hotel is repeated) \n" ); document.write( "so the probability =4*4*4=64 \n" ); document.write( " |
