Question 483293
Data is collected for a total of 100 driving trips. Informatiom is gathered on whether the driver takes a map and whether the driver gets lost (see the table below). The driver then goes on 2 additional trips.
..................Gets lost...............Doesn't get lost..........Totals
....................10..........................30.......................40
....................40..........................20.......................60
....................50..........................50.......................100
Find the probability that the driver gets lost both times, whether a map is brought or not.
-------------
P(gets lost on a trip) = 50/100 = 1/2
---
P(gets lost on 2 trips) = (1/2)(1/2) = 1/4 = 0.25
