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

a

b

Step-by-step explanation:

From the question we are told that

   The probability of the traffic light being green is

   The probability of the traffic light being red is  

   The probability of the traffic light being yellow is  

   The number of days of observation is n = 5

Generally the probability distribution function for a multinomial distribution is mathematically represented as

Generally the probability that P[G=2, Y=1, R=2]

=>

Generally the probability that P[G=R] is mathematically represented as

Here

Also  

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
