Answer:
64.65% probability of at least one injury commuting to work in the next 20 years
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
Each day:
Bikes to work with probability 0.4.
If he bikes to work, 0.1 injuries per year.
Walks to work with probability 0.6.
If he walks to work, 0.02 injuries per year.
20 years.
So
Either he suffers no injuries, or he suffer at least one injury. The sum of the probabilities of these events is decimal 1. So
We want . Then
In which
64.65% probability of at least one injury commuting to work in the next 20 years
Answer:
Option B.
Step-by-step explanation:
Eric states the applied interest is simple interest. We need to check whether the this statement is true or false.
In simple interest, the amount of deposit increased at a constant rate. It means the difference between future values of any two consecutive years will same.
Difference between future values of first two years.
Difference between future values of 2nd and 3rd year is
Since d₁≠d₂, therefore, the given statement is false.
Thus, the correct option is B.
