The answer is number 2. Thirty cents
So the Pythagorean triplet is 8,15and 17
Answer:
0.381 is the probability that the number of drivers will be at most 18.
Step-by-step explanation:
We are given the following information in the question:
The number of drivers who travel between a particular origin and destination during a designated time period has a Poisson distribution with parameter μ = 20.
- The Poisson distribution is the discrete probability distribution of the number of events occurring in a given time period, given the average number of times the event occurs over that time period.
- The variance of Poisson distribution is equal to the mean of Poisson distribution.
a) P(number of drivers will be at most 18)
Formula:


Thus, 0.381 is the probability that the number of drivers will be at most 18.
Simplified answer is 5/8. This is how it has been solved:
1. x - 1/4 = 3/8;
2. x = 1/4 + 3/8;
3. x = 2/8 + 3/8;
4. x = 5/8;
Hope everything is clear.
