Answer: a. 8% ; b. Not independent; c. See tree diagram; d. Yes
Step-by-step explanation:
a. Let F = Females
M = Males
C = Those that attend college
P(F) = 80% = 0.8
P(M) = 20% = 0.2
P(C/F) = 90% = 0.9
P(C/M) = 78% = 0.78
If 90% of the females go to college, it means that 10% don't go to college.
We then use the multiplication rule and we'll get:
= 80% × 10%
= 0.8 × 0.1
= 0.08
= 8%
b. An independent event is one that the occurence of one event doesn't affect the other event from happening. However, this is not independent as the occurence of the events affect each other.
c. See attachment
The joint probability on the tree diagram will be:
= 0.72 + 0.08 + 0.156 + 0.044
= 1.00
