Question
An article in Knee Surgery, Sports Traumatology, Arthroscopy, "Arthroscopic meniscal repair with an absorbable
screw: results and surgical technique," (2005, Vol. 13, pp. 273-279) cites a success rate more than 90% for
meniscal tears with a rim width of less than 3 mm, but only a 67% success rate for tears of 3-6 mm. If you are
unlucky enough to suffer a meniscal tear of less than 3 mm on your left knee, and one of width 3-6 mm on your
right knee, what is the probability mass function of the number of successful surgeries, x? Assume the surgeries
are independent.
Choose the correct answer.
O P(x = 0) = 0.2, P(x = 1) = 0.4, P(x = 2) = 0.4
O P(x = 0) = 0.033, P(x = 1) = 0.42, P(x = 2) = 0.603
O P(x = 0) = 0.067, P(x = 1) = 0.364, P(x = 2) = 0.603
O P(x = 0) = 0.033, P(x = 1) = 0.364, P(x = 2) = 0.603
= 0.067, P(x = 1) = 0.42, P(x = 2) = 0.603
