(85 + 84 + 78 + x) / 4 = 86
(247 + x) / 4 = 86

Jon did determine the probability correctly.
Step-by-step explanation:
<em>In Jon's closet, there are a total of 24 clothes. Among those pieces of clothing, there are a total of 9 out of 24 clothes that are black. There are also 11 shirts out of 24 clothes. </em>
<em />
<em>When a probability has OR in it, it means to add.</em>
