Answer:
i) If you randomly pick 2 gum balls from the drawer,the probability that one will be green and the other will be blue is 2/33
ii)The probability that you will pick 3 yellow gum balls in a row is 3/28
Step-by-step explanation:
Number of green gum balls = 4
Number of blue gum balls = 7
Number of yellow gum balls = 11
Total number of balls = 4+7+11=22
If you randomly pick 2 gum balls from the drawer
We are supposed to find the probability that one will be green and the other will be blue
Probability of getting green ball =[tex]\frac{4}{22}[/tex]
Probability of getting blue ball = [tex]\frac{7}{21}[/tex]
So,the probability that one will be green and the other will be blue = [tex]\frac{4}{22} \times \frac{7}{21} = \frac{2}{33}[/tex]
Probability that you will pick 3 yellow gum balls in a row =[tex]\frac{11}{22} \times \frac{10}{21} \times \frac{9}{20}=\frac{3}{28}[/tex]
i) If you randomly pick 2 gum balls from the drawer,the probability that one will be green and the other will be blue is 2/33
ii)The probability that you will pick 3 yellow gum balls in a row is 3/28
