Answer: Our required probability is 0.618.
Step-by-step explanation:
Since we have given that
Probability of all drivers were involved in a car accident last year = 66%
Number of drivers = 10
Number of drivers involved in a car accident = 3
So, probability of drivers involved in car accident is given by
Probability of getting 3 or more who were involved in a car accident is given by
P(X≥3)=1-P(X=0)-P(X=1)-P(X=2)
Here,
So, our equation becomes
P(X≥3)=1-P(X=0)-P(X=1)-P(X=2)
Hence, our required probability is 0.618.
