Answer #1

Below is the probability for calculation in R. Poisson distribution is calculated using the function ppois().

R Code

# Part a)
# As ,mean occurence lambda = 2 is given poison distribution is calculated.
# For zero or no fish i.e. q = 0
ppois(0, lambda = 2)
# Part b)For fewer than 6 fishses q = 5 is used
ppois(5, lambda = 2)
# Part c) Fishes between 3 and 6, q = 3 is subtracted from q = 3
a <- ppois(5, lambda = 2)
b <- ppois(3, lambda = 2)
a - b
