Short-sleeved Pattern Size PI 0.04 0.02 0.05 M 0.08 0.07 0.12 0.03 0.07 0.08 Long-sleeved Pattern 0.03 02 0.03 M 0.09 0.06 0.07 (a) what the probability that the next shirt sold ong-sleeved, print shirt? is a medium, is (b) What is the probability that the next shirt sold is a medium print shirt? 0.13 shirt? A long-sleeved shirt? (c) What is the probability that the next shirt sold is a short-sleeved short-sleeved shirt 0.56 long-sleeved shirt 0.44 (d) What is the probability that the size of the next shirt sold is medium? What is the probability that the pattern of the next shirt sold is a print?Explanation / Answer
Solution:
a) probability that next shirt is a medium ,long-sleeved and print shirt
= 0.06
b) probability that next shirt sold is a medium print shirt
= 0.06 + 0.07 = 0.13
c) short sleeved shirt = sum of all probability in 1st table = 0.56
long sleeved shirt = 1- 0.56 = 0.44
d)
probability that size of the next shirt is medium = 0.08+ 0.07+0.12 +0.09+0.06+0.07 = 0.49
probability that shirt sold is print = 0.02+0.07+0.07 +0.02+0.06+0.02 = 0.26
