Jack has three coins c1, c2, and c3 with p1, p2, and p3 as their corresponding probabilitiesof landing heads. jack flips coin c1 twice and then decides, based on the outcome, whetherto flip coin c2 or c3 next. in particular, if the two c1 flips come out the same, jack flips coinc2 three times next. however, if the c1 flips come out different, he flips coin c3 three timesnext. given the outcome of jack’s last three flips, we want to know whether his first two flipscame out the same. describe a bayesian network and a corresponding query that solves thisproblem. what is the solution to this problem assuming that p1 = .4, p2 = .6, and p3 = .1and the last three flips came out as follows: (a) tails, heads, tails(b) tails, tails, tails

Let denote the event that the two flips yield the same faces (1 if the same faces occur, 0 if not), so that

For example,

Let denote the outcome (number of heads) of the next three flips of either or . By the law of total probability,

and in particular we have

Then

Jack wants to find for some given .

a. With , we have

b. With , we'd get

where is the rest of the

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
