Suppose the tree diagram below represents all the students in a high school and that one of these students were chosen at random. if the student is known to be a girl, what is the probability that the student is right-handed? a. 1/4 b. 3/4 c. 5/6 d. 1/6

The Answer is C 5/6

250/300 reduced and simplified is 5/6

The probability that the student is right-handed given that the student is a girl is:

Step-by-step explanation:

From the tree diagram we have to find the probability that the students is right handed given that the student is a girl.

Let A denote the event that the student is a girl.

and B denote the event that the student is right handed.

We are asked to find the probability:

P(B|A)

We know that P(B|A) is calculated as:

There are a total of 500 students.

Out of which 300 are girls.

( i.e.    )

and out of 300 girls 250 are right handed.

( i.e.  )

Hence,

Hence,The probability that the student is right-handed given that the student is a girl is:

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
