Suppose each day that you drive to work a traffic light that you encounter is either green with probability 3/8, red with probability 1/2, or yellow with probability 1/8, independent of the status of the light on any other day. If over the course of five days, G, Y, and R denote the number of times the light is found to be green, yellow, or red, respectively, what is the probability that P[G=2, Y=1, R=2] ? Also, what is the probability P[G=R]? [15%]. Hint: consider sequences possible in a five-day observations
Answer:
a
[tex]P(G = 2 , Y= 1 , R = 2) = 0.13184 [/tex]
b
[tex]P(G = R ) = 0.13919 [/tex]
Step-by-step explanation:
From the question we are told that
The probability of the traffic light being green is [tex]p_g = \frac{3}{8}[/tex]
The probability of the traffic light being red is [tex]p_r = \frac{1}{2}[/tex]
The probability of the traffic light being yellow is [tex]p_y = \frac{1}{8}[/tex]
The number of days of observation is n = 5
Generally the probability distribution function for a multinomial distribution is mathematically represented as
[tex]Pr( X_1 = x_1 \ and \ . . . \ and \ X_k =x_k) = \left \{ {{ \frac{n!}{x_1 ! , . . . x_k !} p_1^{x_1} * \cdots *p_k^{x_k} \ \ \ \ \ \ \ when \ \sum x_i = n } \atop {0 }\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ otherwise \ } \right[/tex]
Generally the probability that P[G=2, Y=1, R=2]
[tex]P(G = 2 , Y= 1 , R = 2) = \frac{5!}{ 2! * 1! * 2!} * [\frac{3}{8} ]^2 * [\frac{1}{8} ]^1 * [\frac{1}{2} ] ^2[/tex]
=> [tex]P(G = 2 , Y= 1 , R = 2) = 0.13184 [/tex]
Generally the probability that P[G=R] is mathematically represented as
[tex]P(G = R ) = P( G = 2 , Y = 1 , R = 2) + P( G = 0 , Y = 5 , R = 0)+ P( G = 1 , Y = 3 , R = 1)[/tex]
Here
[tex] P( G = 0 , Y = 5 , R = 0) = \frac{5!}{ 0! * 5! * 0!} * [\frac{3}{8} ]^0 * [\frac{1}{8} ]^5 * [\frac{1}{2} ] ^0[/tex]
[tex] P( G = 0 , Y = 5 , R = 0) = 0.0000305176 [/tex]
Also
[tex] P( G = 1 , Y = 3 , R = 1)= \frac{5!}{ 1! * 3! * 1!} * [\frac{3}{8} ]^1 * [\frac{1}{8} ]^3 * [\frac{1}{2} ] ^1[/tex]
[tex] P( G = 1 , Y = 3 , R = 1)= 0.0073242 [/tex]
[tex]P(G = R ) = 0.13184 + 0.0000305176+ 0.0073242 [/tex]
[tex]P(G = R ) = 0.13919 [/tex]

Question 1
Sione just landed a great job as an engineer where he will make $55,000 a year. The
company he will work for guarantees a 3% pay increase each year so it's employees
salaries keep up with inflation. At the end of the 1* year Slone will have made $55,000
dollars.
1. What is the recursive function that will represent this situation?
a. m(t) = m(t - 1) + 0.03, m(1) = 55000
b. m(t) = m(t-1). 0.03, m(1) - 55000
c. m(t) = m(t-1) + 1.03, m(1) - 55000
d. m(t) = m(t-1). 1.03, m(1) = 55000
Answer:
Option (d)
Step-by-step explanation:
If the current salary of Sione is represented by the function m(t - 1),
Next year his salary m(t) gets hike of 3%.
So, the next year salary of Sione will be represented by,
m(t) = m(t - 1) + 3% of m(t - 1)
= m(t - 1) + 0.03 × m(t - 1)
= m(t - 1)(1 + 0.03)
= 1.03m(t - 1)
Since, at the end of year 1 his salary was $55000,
Recursive function will be,
m(t) = 1.03m(t - 1) = 55000
Therefore, Option (d) will be the answer.

Answer:
(1) n = 9
(2) n = 15
(3) r = -8
Plz mark brainliest:)
Answer:
n=9n=15r=-8Step-by-step explanation:
1.4=n/9+3
4-3=n/9
1=n/9 cross multiply
2. -7=-8+n/15
-7+8=n/15
1=n/15 Cross multiply
n=15
3.-11=r/2-7
-11+7=r/2
-4=r/2cross multiply
-8=r
r=-8

Write the slope-intercept form of the equation of the line.
-4 - y = -2x
A) y = 4x + 2
C) y = 2x - 4
B) y = -4x + 2
D) y = -2x + 2
Answer:
c
Step-by-step explanation:
-4 -y = -2x
+4 +4
-y = -2x + 4
multiple everything by -1 to get y by itself
y = 2x - 4

A triangle has sides with lengths of 42 millimeters, 43 millimeters, and 58 millimeters. Is it a
right triangle?
Answer:
No
Step-by-step explanation:
42 x 42 = 1764
43 x 43 = 1849
1764 + 1849 = 3613
and the sqaure roof of 3613 is 60.11
60.11 does not equal 58
so no it is not a right triangle
