1. consider drawing a single card from a well shuffled 52-card deck. let e1 be an event of getting a heart card and e2 be an event of getting a face card. find p(e1ue2). 2. two balls are drawn in succession, without replacement, from a box containing 4 blue and 6 white balls of the same sizes. what is the probability of drawing a blue ball on the first draw and a white ball on the second drawn?

1)
Let E be the event E1UE2, that is: "getting a heart card or a face card."

There are a total of 13 hearts and 3+3+3 non hearts face cards.
Thus, n(E)=13+9=22.

P(E)=n(E)/52=22/52=0.423

2)
The probability of drawing first a blue ball is 4/10=2/5. After a blue ball has been drawn, now there are 3 blue and 6 white balls left. Thus, the probability of now drawing a white ball is 6/9=2/3.

The probability of this event to happen is (2/5)*(2/3)=4/15=0.267

There is no question, there is just the answer.
