Answer:
A card cannot be both a jack and 10 at the same time.
(The events are mutually exclusive; can't occur at same time.)
Explanation:
When drawing a single card at a time, the card cannot be a jack and 10 at the same time.
P(Jack or 10) would be a different story. There are 4 of each kind in a deck so the P(Jack or 10)=8/52=4/26=2/13.
