Table and chairs

Four people should sit at a table in front of a row of 7 chairs. What is the probability that there will be no empty chair between them if people choose their place entirely randomly?

Correct answer:

p =  0.1143

Step-by-step explanation:

C4(7)=(47)=4!(74)!7!=321765=35  n1=(47)=35 n2=4 n3=0 p=n2/n1=4/35=0.1143
