Example 3.16 from Statistics, 3.3 Two Basic Rules of Probability
e. Are being a novice swimmer and practicing four times a week independent events? Why or why not?
Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.
e. No, these are not independent events.
P(novice AND practices four times per week) = .0667
P(novice)P(practices four times per week) = .0996
.0667 ≠ .0996
How did it go?
