Answer:
Total number of cards in a standard deck of card=52
As deck of card contain 13 club +13 heart +13 spade+13 Diamond.
P(Diamond)=13/52 =1/4
If the card is not diamond then
P(not diamond)=39/52=3/4
Since after drawing card is not replaced
P ( second Diamond)=12/51
now if second card is not Diamond.then
P(non diamond)=39/51
Chances of your winning i.e both cards are diamonds=1/4×12/51=1/17=0.0588..(approx)
chances of your friend winning=1/4×39/51=[1/4]×[13/17]=13/68=0.1911..(approx)
Your friend has got better chance to win because there are more chances that both the cards are not Diamonds.
The answer is 91 ............
You first have to plug in your given numbers to the equation.
d= rt
d=(52)4.5
Then you solve
52*4.5 = 234
So, your distance or d=234
How much are the owner's expenses for 10 days?
10 * 130 = $1300
How much money does the owner make selling pizzas per day?
200 * 3 = $600
How much money does the owner make selling sandwiches per day?
85 * 2 = $170
In one day, the owner sells 600 + 170 = $770 worth of pizza and sandwiches
Over the course of ten days, that is 10 * 770 = $7700
Profit = revenue - cost = 7700 - 1300 = $6400
There ya go
Option 3 should be correct. Use rise over run.
