a) Determine the number of points in the sample space. The number of points in teh sample space is ____________
b) If the couple randomly selects one of the combinations, determine the probability the couple selects a maple tree. The probability is ______. (Simplify your answer)
c) Find the probability that the couple selects a dogwood tree and a barberry shrub. The probability is_______. (Simplify your answer).
d) Find the probability that the couple selects a lilac bush other than Sensation. The probability is_______. (Simplify your answer)
| Tree | Shrubs | Lilac bushes | 
| Maple | Juniper | Anabel | 
| Dogwood | Forsythia | Sensation | 
| Pine | Barberry | 
Solution
a)the number of points in sample space= no of trees *no of shrubs *no of lilacs=3*3*2=18
b)total different trees= 3
Therefore maple tree selection probability=1/3=0.33
c)the number of chances to select a dogwood tree and barberry shrub=2
Hence probability=2/18=O.11
d)there are two types of lilacs
Probability of selecting a lilac other than sensation =1/2=0.5
