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:
midpoint of (2,4) and (2,8) is <u>( 5 , 3 )</u>
Step-by-step explanation:
your answer!
F:m:s=4:5:7
s=f+18 and from above we see s/f=7/4 so s=7f/4 now we can say:
f+18=7f/4
4f+72=7f
3f=72
f=24 and we know s=f+18 so
s=42
m/s=5/7 so m=42*5/7=30
So Frank got 24, Mary got 30, and Seth got 42.
