One of two small classrooms is chosen at random with equally likely probability, and then a student is chosen at random from the chosen classroom.
classroom #1 has 5 boys and 13 girls.
classroom #2 has 14 boys and 9 girls.

what is the probability that classroom #2 was chosen at random, given that a girl was chosen?

Our required probability is 0.351.

Step-by-step explanation:

Since we have given that

Probability of getting classroom 1 =

Probability of getting classroom 2 =

Probability of getting girl from classroom 1 =

Probability of getting girl from classroom 2 =

Using "Bayes theorem".

so, the probability that classroom 2 was chosen given that a girl was chosen would be

Hence, our required probability is 0.351.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

a - base

b - exponent

so,
