Event=200 or more cars
The number of cars was counted on 10 days and thus there were 10 trials.
# of trials=10
200 or more cars were counted on 9 of the 10 days and thus the event occurs 9 times.
# of times the event occurs= 9
The probability is the number of times the event occurs divided by the number of trials:
P ( 200 or more cars)= # of times the event occurs / # of trials
=9/10
0.9
90%
We know that the sum Of the probabilities Of an event And it’s Complement needs to be equal to 1.
P( event ) + P ( complement)= 1
What is it is “200 or more cars”
P( 200 or more cars) + P (not 200 or more cars) = 1
Since P ( 200 or more cars) = 9/10 we can replace P ( 200 or more cars) in the equation by 9/10
9/10 +P ( not 200 or more cars) =1
Subtract 9/10 from each side
-9/10= 1-9/10
Combine like terms
P( not 200 or more cars) = 1/10= 0.1 = 10%
A: 9/10 = 0.9 = 90%
B: 1/10= 0.1= 10%
