Answer
$\frac{3}{5}$
Work Step by Step
The probability of event B, assuming that the event A has already occurred, is called the conditional probability of B, given A. This probability is denoted by P(B|A).
E: An odd number, given that a red disk is selected.
A: There are 5 red disks.
B: There are 3 red disks with odd numbers: 1, 3, and 5.
Thus, we have:
P(B|A) = $\frac{3}{5}$
