Answer:
P(1≤X≤3) = 0.5974
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.
Mean of 3
This means that 
P(1≤X≤3) ?

So




So

Answer:
I am a little confused by your question but if you were getting less it would be the first but more would be the second
Step-by-step explanation:
Answer:
$475
Step-by-step explanation:
There are 3 possible accident in this question
3% chance of losing $2000
0.1% chance of losing $150,000
96.9% chance of losing $0
Then the expected value that you will lose is:
3%* $2000 + (0.1% * $15000) + (96.9% * $0)= $75
Profit made by subtracting the price with the lose. If the company want average profit $400, the charge should be:
average profit = premium price - average lose
premium price= average profit + average lose
premium price= $400 + $75 = $475
A ratio is a comparison of two numbers that can be written in multiple ways such as:
Word: There are ___x for every ___ y
Fraction: y/x
Ordered pair: (x,y)
Ratio:x:y
Proportional is a type of relationship where, oh a graph, a line goes through the 0,0 point and when you divide y/x at any point, you will get the same answer.
Hope this helped!
