a) 10 weeks

b) P(k≤2)=0.190

c) P(k>17)=0.167

Step-by-step explanation:

This problem can be solved applying the geometric distribution.

The probability of needing k weeks to find an acceptable apartment can be written as:

a) The expected value of this distribution is:

10 weeks

b) The probability of finding an acceptable department in the first 2 weeks is:

c) We have to calculate P(k>17)
