Answer:
a)
And we can find the individual probabilities like this:
And replacing we got:
b)
Step-by-step explanation:
Let X the random variable that represent the number of hurricanes hitting the coast of Florida annualle. We know that
The probability mass function for the random variable is given by:
And f(x)=0 for other case.
For this distribution the expected value is the same parameter
Part a
For this case we want this probability:
And for this case we can use the complement rule like this:
And we can find the individual probabilities like this:
And replacing we got:
Part b
Using the probability mass function we have:
Answer:
807,205
Step-by-step explanation:
Take the eight hundred and seven thousand and express that has 807,000. Then, add the two hundred and five at the end to get 807,205
