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) = $\frac{3}{5}$
