From 27 pieces of luggage, an airline luggage handler damages a random sample of four. The probability that exactly one of the d
dusya [7]

Answer:

0.273

Step-by-step explanation:

Let the number of insured pieces of luggage be <em>i</em> and <em>u</em> be the number of uninsured pieces of luggage, therefore,

<em>i </em>+ <em>u </em> = 27

Now,

probability that exactly one of the damaged pieces of luggage is insured = (iC1)(uC3)/(27C4)

probability that none of the damaged pieces are insured = (uC4)/(27C4)

and,

(iC1)(uC3)/(27C4) = 2 (uC4)/(27C4)

=> <em>u − </em>2<em>i </em>= 3

By solving, <em>i </em>+ <em>u </em> = 27 and  <em>u − </em>2<em>i </em>= 3

<em>i</em> = 8 and <em>u</em> = 19

and,

(8C2)(19C2)/(27C4) = 0.273
