Answer:
0.1 = 10% probability that more than 4 people arrive in a vehicle
Step-by-step explanation:
We have these following probabilities:
0.2 probability that 1 people arrive in a vehicle.
0.35 probability that 2 people arrive in a vehicle
0.25 probability that 3 people arrive in a vehicle
0.1 probability that 4 people arrive in a vehicle
x probability that more than 4 people arrive in a vehicle.
What is the probability that more than 4 people arrive in a vehicle?
The sum of all probabilities is 1 = 100%. So
0.2 + 0.35 + 0.25 + 0.1 + x = 1
x = 0.1
0.1 = 10% probability that more than 4 people arrive in a vehicle
