Mr Chan spent

dollars when he bought the shares. If he sells 45 shares at 3.80, he will gain

dollars. So, the net profit would be

Answer:
v - w - 1
Step-by-step explanation:
Try an experiment with a small, specific set of numbers like:
4, 5, 6, 7, 8, 9, 10 w = 4 and v = 10.
There are 5 numbers in the list, not counting the first and last. Is this related to the difference between v and w? v - w = 6, one more than 5.
The number of natural numbers between w and v, not including w and v, is v - w - 1.
The probability that an ear of corn selected at random with no borers is 0.5488
Given,
The farmer counted 3000 borers in the 5000 ears.
The probability mass function of Poisson distribution: 
Here,
is the parameter.
Then the value of parameter is:
= 0.6
Now determine the probability that an ear of corn selected random will contain no borers:
P(X=0) = 
P(X=0) = 
P(X=0) ≈ 0.5488
