<u>Given</u>:
The given expression is
We need to determine the equivalent number.
<u>Equivalent expression:</u>
To determine the equivalent number, let us solve the expression
Thus, let us apply the exponent rule , we get;
Also, the term 10³ can be written as
Thus, we get;
Dividing, we get;
0.001
Hence, the equivalent number is 0.001
Hence, Option c is the correct answer.
Using the binomial distribution, it is found that there is a 0.7215 = 72.15% probability that between 10 and 15, inclusive, accidents involved drivers who were intoxicated.
For each fatality, there are only two possible outcomes, either it involved an intoxicated driver, or it did not. The probability of a fatality involving an intoxicated driver is independent of any other fatality, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- 70% of fatalities involve an intoxicated driver, hence
.
- A sample of 15 fatalities is taken, hence
.
The probability is:
Hence
Then:
0.7215 = 72.15% probability that between 10 and 15, inclusive, accidents involved drivers who were intoxicated.
