Three houses are available in a locality. Three persons apply for the houses. Each applies for one house without consulting others. The probability that all the three apply for the same house is
Explanation
Concept:
P(E) = Probability of an event E
P(E)=Total outcomeFavourable outcome
Number of ways of choosing m objects by n people with no restriction = mn
Calculation:
Given
number of house (m)=3
number of people applying for house (n)=3
total number of way three people can apply for house = 33=27
Number of way in which all people apply for same house = 3
P(all three applying for same house)=273=91
