Decide whether the two events are disjoint and tell why or why not:

• randomly drawing a jack from a standard deck of cards

• randomly drawing an ace from a standard deck of cards

a)disjoint, because the events cannot occur at the same time.

b)not disjoint, because the events can occur at the same time.

c)not disjoint, because the events cannot occur at the same time.

d)disjoint, because the events can occur at the same time.
