Question 233473: it is claimed the 75% of drivers wear seatbelts. assuming that this is true, find the probability that out of four randomly selected drivers, none wear seatbelts.
So, is the probability of wearing a seatbelt 0.5 or 0.75?

You can put this solution on YOUR website! it is claimed the 75% of drivers wear seatbelts. assuming that this is true, find the probability that out of four randomly selected drivers, none wear seatbelts.
So, is the probability of wearing a seatbelt 0.5 or 0.75?
-------------
If you were to pick a driver at random the probability
that person wore seat belts is 0.75
The probability that person did not wear seat belts is 0.25.
------------------------
P(none of 4 wear seatbelts) = (0.25)^4 = 0.0039
