Answer:
c. 0.55
Step-by-step explanation:
A chosen acre of land is forested and not forested are complimentary event , so let
:
F = Chosen land is forested
F = Chosen land is not forested
....and we know F+F = S
where S is sample space and we know probability ocer whole sample space is 1 , that is P(S)=1 , and we know F and F are independent so
P(F+F) = P(S)
P(F) + P(F)=1
We have given that probability of forest land in randomly chosen an acre land in Canada have probability 0.45 so P(F)=0.45 so
,
0.45 + P(F) = 1
P(F) = 1 - 0.45
P(F) = 0.55
Hence, the probability that the chosen acre is not forested is 0.55
