Recall from Example 1 that whenever Suzan sees a bag of marbles, she grabs a han and two purple ones. She orabs five of them. Find the probablty of the following event, expressing t as a faction in lowest terms dful at random. containing three red marbles, two green ones, three white ones She has seen a bag HINT (See Example 1.) She has two green ones and one of each of the other colors. Recall from Example 1 that whenever Suzan sees a bag of marbles, she orabs a handful at random. She has seen a bag containing two red marbles, four green ones, two white ones, and qne purple one. She grabs six of them. Find the probability of the following event, expressing it as a fraction in lowest terms. HINT (See Example 1.) She does not have all the red ones.

1) sample space = 3+ 2 + 3+2 = 10
10C 5 = 252
probability of 2 green = 2 /2
probability of selecting 1 from each = 1* 3 * 3*2 = 18
total probability = 18 / 252
= 1/14
2) 2 red , 4 green , 2 white , 1 purple
sample space = 9C 6 = 84
finiding probability that she has all red = 2C2 = 1
7C4 = 35
probability = 35/84
= 5/12
then probability of not all red 1 - 5/12
= 7/12
