Answer:
Let X be the number of times the target is hit. The probability P(X≥1) then equals 1 minus the probability of missing the target three times:
P(X≥1) = 1− (1−P(A)) (1−P(B)) (1−P(C))
= 1−0.4*0.3*0.2
= 0.976
To find the probability P(X≥2) of hitting the target at least twice, you can consider two cases: either two people hit the target and one does not, or all people hit the target. We find:
P(X≥2)=(0.4*0.7*0.8)+(0.6*0.3*0.8)+(0.6*0.7*0.2)+(0.6*0.7*0.8) = 0.788

Answer:
Eric
Step-by-step explanation:
First, we determine the distance of each player to the hole using the distance formula.
Given points
Distance
<u>Eric</u>
The hole is at (3,2)
Eric's golf ball is at point (-6,6)
Distance=
<u>Cam</u>
The hole is at (3,2)
Cam's golf ball is at point (8,-6)
Distance=
<u>Brooke</u>
The hole is at (3,2)
Brooke's golf ball is at point (10,8)
Since Eric's ball is the farthest from the hole, Eric should shoot next.
The simplified form of the provided expression of 2 startroot 18 endroot +3 startroot 2 endroot startroot +162 endroot is 18√2.
<h3>What is the simplified form of an equation?</h3>
The simplified form of an equation is the simplest way of expressing the equation, by applying the required operations of mathematics.
The equation provided in the problem is,
Let the simplified form of the above expression is <em>n. </em>Thus,
Rewrite the equation to solve it further as,
The square of the term cancel out the square root of it. Thus,
Thus, the simplified form of the provided expression of 2 startroot 18 endroot +3 startroot 2 endroot startroot +162 endroot is 18√2.
