Assume that all (525)poker hands are equally likely. What is the probability that you will be dealt:
AlekseyPX

Answer:

There is 1.98% of probability of being dealt a flush in 5-card Poker

Step-by-step explanation:

To know the probability of a flush being dealt, we can calculate the number of cases when that happens and divide it by the total number of cases of poker hands that exist, naming A the event of a flush.

We will use combinations (nCr button on a calculator) to count the number of cases, because we don't care about the order (it is the same to be dealt a 2, 4, 6, 7 and 8 of hearts than the opposite order), being a flush the event when we take 5 cards out of 13 of the same suit, times 1 out of 4 possible suits and the total number of cases is taking 5 random cards out of 52.

P_{A} =\frac{Cases   Of Flush}{Hands} =\frac{\left(\begin{array}{ccc}13\\5\end{array}\right)*\left(\begin{array}{ccc}4\\1\end{array}\right)}{\left(\begin{array}{ccc}52\\5\end{array}\right)} =\frac{5148}{2598960}=0,00198\\

That means there is about a 2% of probability of being dealt a flush.

In other words, of every 16660 plays, 33 will be, on average, a flush

Tom is 4 more than twice andrews age. Sara is 8 less than 5 times ANdrews age. If tom and sara are twins how old is andrew
fgiga [73]

Answer:

there

Step-by-step explanation:

T = 4 + 2A

S = 5A - 8

T = S

Since T and S are equal, set them against each other

2A + 4 = 5A - 8

Subtract 2A from each side, and add 8 to each side

12 = 3A

Divide each side by 3

A = 4

If Andrew is 4, then Tom is twice that plus 4, or 12. Sarah is 5 times 4 less 8, or 12.
