The probability of purchasing mineral rights to exactly one of the two mountains is 0.51.
<h3>What is probability ?</h3>
Probability turned into added into arithmetic to are expecting the possibility of an occasion occurring. Probability essentially approach how in all likelihood it's miles that some thing will happen. This is the fundamental principle of possibility and is likewise utilized in possibility distributions to examine feasible consequences of random experiments.
<h3>Calculation</h3>
Given information:
A company is considering purchasing materials:
The probability of purchasing mineral rights
Form the first mountain P1 = 0.55
From the second mountain P2 = 0.4
As the decision is made independently
So, P(P2∩ notP1) = 0.55 * 0.6
P(P2∩ notP1) = 0.33
Similarly, the value of
P(P2∩ notP1) =0.4 * 0.45
P(P2∩ notP1) = 0.15
Hence ,
P = 0.33 + 0.18
P = 0.51
Hence , the probability of purchasing mineral rights to exactly one of the two mountains is 0.51.
