Answer:
(25,19)
Step-by-step explanation:
We are to find the location of the train station.
Using the formula for calculating midpoint given as:
M(X,Y) = [(x1+x2)/2, (y1+y2)/2]
X = x1+x2/2
Y = y1+y2/2
Given
M(X,Y) = (11,11)
Bus station (x1, y1) = (-3,3)
Substituting the given parameters into the formula.
11 = -3+x2/2
Cross multiply
11×2 = -3+x2
22 = -3+x2
x2 = 22+3
x2 = 25
Similarly
Y = y1+y2/2
11 = 3+y2/2
Cross multiply
11×2 = 3+y2
22 = 3+y2
y2 = 22-3
y2 = 19
Hence the location of the train station is at (25,19)

<u>Total number of beads:</u>
(i)
<u>Probability of 2 red:</u>
- P(RR) = 15/25*15/25 = 9/25
(ii)
<u>Probability of no 2 red:</u>
- P(R'R') = 1 - 9/25 = 16/25
