Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (1, 2) and (x₂, y₂ ) = (5, 4)
m =
=
= 
We can use the multiplicative rule since these are independent events. If the probability that one given flight takes place is 0.81, then the probability of 3 flights taking place is (0.81)^3 = 0.5314.
