7 females, and 5 males including Larry.
There are 4 tasks to be assigned. Note that assigning the same
people different tasks constitutes a different assignment.
(1) Find the probability that both males and females are given a task.
(2) Find the probability that Larry and at least one female
are given tasks.

I feel like a math bum :)

- Directrix

Don't feel. Just work. Post the other 12 or 13 problems individually on this site. You do that while I work on this problem. I may have to stop and eat some brain food. :} You need to focus. Nobody here is a bum.

is that the final solution

ha ha i post them wuickly

- anonymous

quickly

- Directrix

P(both genders) = 1 - { [ C(7,0) C(5,4) - C(7,4) C(5,0)] / C(12,4) } = 1 - 40/495 = 455/495 = 91/99 = .919 approx

- anonymous

Correct

- anonymous

So the second part would be similar?

- Directrix

P(Larry and at least 1 F)
P(at least 1F) = 1 - P(0F) = 1 -{ [C(7,0)C(5,4)] } / C(12,4) = 5/495 = 490/495 = 98/99 = .99 ish.
Ways to choose Larry = 1 C(1,1) = 1
P(Larry and at least 1 F) = 1(98/99) = 98/99 = .99 approx

- anonymous

no it didnt work

- anonymous

larry wouldnt be 5?

- anonymous

5,1

- Directrix

But, we want Larry and none of the other males. So P(Larry) = C(1,1) C(4,0) = 1. That would be Larry and none of the other males.

- Directrix

I'm going to cases for this. Slow but may make more sense.

- anonymous

how ya doing

- Directrix

Larry and at least 1F
--------
Cases
{Lar, 1F, 2 other M}; {Lar, 2F, 1 other M}; and {Lar, 3F, 0 other M}

- Directrix

Ways to choose Lar, 1F, 2 other M} = 1 C(7,1) C(4,2) = 42
Ways to choose {Lar, 2F, 1 other M}; = 1 C(7,2) C(4,1)= 84
Ways to choose {Lar, 3F, 0 other M} = 1 C(7,3) C(4,0) = 35
Ways to choose 4 from 12 is C(12,4) = 495
P(L and at least 1F) = [42 + 84 +35] / 495 = 161/495 =.325 approx

- anonymous

CORRECT! You are a genius....
I have posted some more.
I haven't wanted to post to many at a time and flood the screen

- anonymous

I am wrong no matter what i do on these

- Directrix

Let's find another problem.

- anonymous

I used a lot of the work i learned from hear that helped me on the test in some of these.
