Measrements for the length and width of a rectangular plastic covers for CDs are Tonded to the nearest mm (so they are discrete), Let X denote the length and Y denote the width. The possible values of X are 129, 130, and 131 mm The possible values of Y are 15 and 16 mm. The joint distribution is given by the following table: X=length 129 130 131 Y=width 15 0.12 0.42 0.06 16 0.08 0.28 0.04 The probability that a CD cover has width of 16 mm knowing that it has a length of 129 m Is O 0.4 0.08 O 0.2 O 0.13

Question
Measurements for the length and width of a rectangular plastic cowers for CDs are
Tounded to the nearest mm (so they are discrete). Let X denote the length and Y
denote the width. The possible values of X are 129, 130, and 131 mm. The
possible values of Y are 15 and 16 mm. The joint distribution is given by the
following table:
X=length
129 130 131
Y=width 15 0.12 0.42 0.06
16 0.08 0.28 0.04
The probability that a CD cover has width of 16 mm knowing that it has a length of 129
O 0.4
O 0.08
O 0.2
O 0.13
< O O
O O O O
