Suppose that 3 cards are drawn from a well-shuffled deck of 52 cards. What is the probability that all 3 are diamonds?
Marat540 [252]

There are 13 diamonds in the deck, so \dbinom{13}3 ways of drawing 3 diamonds.

There is a total of \dbinom{52}3 ways of drawing any 3 cards from the deck.

So the probability of drawing 3 diamonds is

\dfrac{\binom{13}3}{\binom{52}3}=\dfrac{11}{850}\approx0.012941

where \dbinom nk=\dfrac{n!}{k!(n-k)!}.

What is the probability from a two way table ?
vladimir1956 [14]
You may remember the two way relative frequency table where each entry in the table is divided by a total from the table. When each cell is divided by the table total (in this case 240), you get a two way whole table relative frequency. (There are also row and column relative frequency tables.)

What does h equal? <br> 36=4(h+2)
tekilochka [14]

Answer:

h=7

Step-by-step explanation:

Distribute the 4 on the right side

36=4(h+2)

36=4h+8

Subtract 8 on both sides

28=4h

Divide by 4 on both sides

h=7

Hope this helps! :)
