Step-by-step explanation:
Percentage involved in accident = 8% = 0.08
Number of drives selected = 14
Probability that 3 or more who were involved in a car accident last year?
P(x>=3) = P(x=3) or P(x>3)
Similarly;
P(x>=3) = 1-P(0<= x <=2)
P(x>=3) = 1-P(0<= x <=2)
Using the binomial probability calculator :
Cummulative probability :
P(X >= x) = 0.09583481948
= 0.0958
