You have a bag with 45 marbles: 20 red, 15 green, 10 blue. You're drawing six. What are the odds they're all red? What are the odds they're all the same color?

For the first, I'm just flat-out doing (20/45)*(19/44)*(18/43)*...*(1... I think that's the right way, but I'm not positive.

For the second, I think it's ((20/45)*...*(15/40))+((15/45)... - or, to sum it up, the odds of each all-one-color result.

Is that the right way to do this?

Solve each equation. Then check your solution.

Please help me on this! Thanks in advance. :)

For both of these math questions, it seems like there is no solution. Am I doing this correctly?

5y - 2y = 3y + 2

My current answer is 0=2, no solution. Is this correct?

And another question. Please and thank you.

3(a+1) - 5 = 3a-2

So what will the Gov and people do when they find that all this "reality" is only the result of an equation that ends with the exsistance of all turning back into something else...

My thoughts is nothing, the dumbing down of America is in full effect....

Science proved that we only have 50 years worth of fuel left, and 100 years of life supporting forests but what do people do.....drink beer, watch TV and live their dull lives as usual
