Answer:
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:
Answer: 10 weeks
b) The probability of finding an acceptable department in the first 2 weeks is:
c) We have to calculate P(k>17)
There are 10 rows of 3 colums of "x"'s, so.. 3x10 or 30 "x"s, and we know that's 5/3 of the original... the original will be one whole or 3/3 or 1
thus
solve for "x"
thus
solve for "x"
