Answer:

$a = \frac{3c - 9b }{10}$

Step-by-step explanation:

10a + 9b = 3c

Subtract 9b to isolate the variable a.

10a = 3c - 9b

Now we need a singular a, so divide equation by 10.

$a = \frac{3c - 9b }{10}$

So that's how you do it.

In this card game, a player is dealt 10 cards. A player wins $1,000,000 if he is dealt 8 hearts. Use combinatorics to set up you

denis23 [38]

Assume a standard deck of 52 cards with 4 suits of 13 cards each.

a. There are $\dbinom{13}8\dbinom{39}2$ ways of being dealt a hand consisting of 8 hearts and 2 non-hearts, so the probability of being dealt such a hand is

$\dfrac{\dbinom{13}8\dbinom{39}2}{\dbinom{52}{10}}\approx0.0000602823$

b. This time, the non-hearts specifically belong to the suit of diamonds, for which there are $\dbinom{13}2$ ways of getting drawn, so the probability is
