Whenever Suzan sees a bag of marbles, she grabs a handful at random. She has seen a bag containing four red marbles, two green ones, five white ones, and one purple one. She grabs eight of them. Find the probability of the following event, expressing it as a fraction in lowest terms.

She has at least one green one.

Step 1

Total number of marbles = 4+2+5+1

=12

Total number of marbles without green = 4+5+1

= 10

Total number of green marbles = 2

Step 2

Let *X* is random variable that represents the number of green marbles.

If she grabs eight of them tha...
