Question

20 POINTS!!!

15. What is the area of ∆DEF shown in the figure? Show your work. (see attachment below)

25. Suppose you draw one card from a standard deck of 52 cards. A standard deck of cards has 4 of each type of card, so the deck contains 4 kings and 4 queens. What is the probability that the card is a king or a queen? Explain.

Answer 1

25.
`(4 + 4)/(52)` =
`(8)/(52)` =
`(4)/(26)` =
`(2)/(13)`

`(2)/(13)` =
`(2*100)/(13)`% = 15
`(5)/(13)`%

Hope this helps you!

Bye!
