Answer:
<u>Jonathan has to pay Faye back US$ 240 </u>
<u>Jonathan has 4 people on his bill and Faye has 6.</u>
Step-by-step explanation:
1. Let's find out the amount of the phone bills, this way:
Total of the two bills = US$ 600
Faye's bill = US$ 120 more than Jonathan's
Jonathan's bill = x
Solving for x, we can use this equation:
x + x + 120 = 600
2x + 120 = 600
2x = 600 - 120
2x = 480
x = 480/2 = 240
<u>Jonathan has to pay Faye back US$ 240 </u>
2. Let's find out the number of people on each bill, this way:
Faye has two people more on her bill than Jonathan
Number of people on Jonathan's bill = x
Number of people on Faye's bill = x + 2
We will use the following equation:
240 * (x + 2) = 360x
240x + 480 = 360x
240x - 360x = -480
-120x = - 480
x = -480/-120
x = 4 ⇒ x + 2 = 6
<u>Jonathan has 4 people on his bill and Faye has 6.</u>
Answer:
A) there are 13 cards per suit and 4 suits, a total of 52 cards. So there are 13*2=26 red cards in a deck of 13*4=52, the odds of drawing a red card are 26/52=1/2=50%
B) Again outside knowledge is required, you name four suits but not their colors. Nonetheless, unless this is a very unusual deck, the diamonds and hearts are red, spades and clubs black. So that’s 2 red suits out of 4 suits. 2/4=1/2=50%
C) there are 2 black suits and 2 red suits. The odds of getting a red card are 2/(2+2)=2/4=1/2 or 50%
Each of those answers is a different way to figure the odds, they come out the same each time, as expected.
However, what if we assume that you mean… when drawing a 5 card poker hand? Or when Penn Jillette asks you “is this your card?”+ Or if you draw every card in the deck? Or if you are playing some macabre game in which you die if you draw the ace of spades but you may only stop drawing if you draw a red card?
There are myriad possible meanings to your question, I’ve just made the simplest assumption and given the odds on that… but my answer is woefully incomplete.
+ Hint, when Penn Jillette asks you “is this your card” your card is always the 3 of clubs. So… 0% chance.
