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.

Answer:
The correct answer is Dale is absolutely wrong.
Step-by-step explanation:
When the cake was complete, it had 360°. When the cake is divided into four halves each half now has 90° each.
Three person including Dale is about to eat the one fourth of the cake, divided among them equally.
Thus each friend gets
° = 30° of cake each.
But Dale claims that each piece of cake has an angle measure if 45°, which is a contradiction as each piece is supposed to to be equal.
Thus Dale is WRONG.
1.01 is bigger. The the 1 is in the hundredth position where as the 9 is in the thousandths position, The further to the left the numbers are larger.
