Answer:
The approximate probability that he or she will be in a car crash during the next year is 0.0275, Yes, it would be unlikely. But it would not be unusual. No, The resulting value is not high enough.
Step-by-step explanation:
Consider the provided information.
Among 400 randomly selected drivers in the 20-24 age bracket, 11 were in a car crash in the last year.
We need to find the approximate probability that he or she will be in a car crash during the next year.
Part(A)
Let P(E) is the probability that he or she will be in a car crash during the next year.
[tex]P(E)=\frac{\text{Favorable Outcomes}}{\text{Total outcomes}}[/tex]
The favorable outcomes is 11 and total number of outcomes is 400.
Substitute the respective values in the above formula.
[tex]P(E)=\frac{11}{400}[/tex]
[tex]P(E)=0.0275[/tex]
Hence, the approximate probability that he or she will be in a car crash during the next year is 0.0275
Part(B)
It is given that an event to be "unlikely" if its probability is less than or equal to 0.05.
0.0275 is less than 0.05
Yes, it would be unlikely. But it would not be unusual.
Part(C)
No, The resulting value is not high enough.
