Answer:
Step-by-step explanation:
Given that Events D and E are independent, with P(D)- 0.6 and P(D and E) - 0.18.
P(D and E) = P(D)*P(E) (since independent)
Or P(E) = 0.3
Using this we find
P(Dor E) = 
QNo2
Since lights are independent
P(Both) = P(A) *P(B) =0.22 where A I light on and B second light on
P(AB') = P(A) P(B') = 0.33
When we add we get P(A) = 0.55
P(B) = 
the probability that the second light will be red when he reaches it
= P(B) = 0.60
Replace x with 10 and simplify the fraction.
40/10 = 4/1 = 4
The answer is 4

Answer:
The position of David Beckham is at (2,0) and the position of the garbage can is (38,0). Note that these two points would be the roots of the parabola we are going to draw.
Now since we have the roots, we can construct the equation of the parabola as
where a is a constant.
We choose a = 0.05 and get
I'd say option D because you can just tell right off the bat that if x = 0, then f(x) = 43.75.
