So,

I have a bag containing 10 blue marbles and 5 red marbles. If I draw 8 marbles without replacement, what is the probability of me getting 1 red marbles out of 8?

2 out 8; 3; 4;5?

How do you calculate that?

Additionally, how would you calculate the probability of my gettingat least1 red marbles out of 8? At least 2; 3; 4; 5?

And how do you calculate that?

Thanks
