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:
6/4 =rise/run
3/2 if it was simplified
98% sure that's corresponding angles.
Could you explain the question more in the comment so I can help?
Answer:
3.3, 3.3031, 3.403, 3.43
Step-by-step explanation:
When you start you start at the very far left and go over from each number until you reach the end to see which one has a higher value then the other itself.
