Compute Probabilities Using the General Multiplication Rule
-Numbered disks are placed in a box and one disk is selected at random. If there are 6 red disks numbered 1 through 6, and 8 yellow disks numbered 7 through 14 , find the probability of selecting a red disk, given that an odd-numbered disk is selected.
A) $\frac { 3 } { 7 }$
B) $\frac { 4 } { 7 }$
C) $\frac { 3 } { 14 }$
D) $\frac { 2 } { 7 }$

Given that an odd-numbered disk is selected, we need to find the probability of selecting a red disk. There are 3 odd-numbered red disks (1, 3, 5) and 4 odd-numbered yellow disks (7, 9, 11, 13), making a total of 7 odd-numbered disks. Therefore, the probability of selecting a red disk given that an odd-numbered disk is selected is $\frac{3}{7}$.
