Question

Julie has two formal events to go to--one for her work and one for her partner's work. She has six formal dresses--two blue ones, one black, one red, and two white. Since the same people will not be at the two events she is okay wearing the same dress. She finds the probabilty that she wears a blue and a red dress as p(blue and red) = 2 6 · 1 6 . What do you know about the two events?

Answer 1

Explanation:

Answer 2

The two events are independent.

Since she does not mind wearing the same dress to both events, the probability of the second event is not changed by the first event occurring. This means the events are independent.
