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.

Answer:
8 more teachers
Step-by-step explanation:
Since 15% of the committee are parents of students, 45% are teachers from the current high school, 25% are school and district administrators, the total percentage is
→ 15 + 45 + 25 = %85
The remaining percentage is 15, and it is equal to 6 students. Then, the total number of people in the committee is
→ 
= 
→ x = 40
Since %45 of the committee are teachers, the number of teachers is
→ 40(
) = 18
Since %25 of the committee are school and district administrators, the number of school and district administrators is
→ 40(
) = 10
That means, there are 18 - 10 = 8 more teachers
