Question

Find the indicated probability. Round to three decimal places.
A car insurance company has determined that 7% of all drivers were involved in a car accident last year. Among the 19 drivers
living on one particular street, 4 were involved in a car accident last year. If 19 drivers are randomly selected, what is the
probability of getting 4 or more who were involved in a car accident last year? (Hint: use binomial probability).

Answer 1

Answer:

explanation below

Step-by-step explanation:

so in order for all 19 drivers to not be in a car accident the probability is

.93 ^ 14 which is around 0.362,

next for 18 of the drivers no accident its

.93^13 x .07 x 19 = around .518

for 17 drivers,

.93^12 x .07^2 x 171 = around .350

for 16 drivers,

so on and you can do the rest
