According to the general equation for conditional probability, if (image attached)

a.
b.
c.
d.

Option A

Step-by-step explanation:

In a probabilistic experiment, when two events A and B are dependent on each other, then the probability of occurrence A since B occurs is:

Then if and then:

Correct choice is A. .

Step-by-step explanation:

Given that , .

Now using those values , we need to find the value of .

So apply the formula of conditional probability:

Plug the given values into above formula,  we get:

Hence correct choice is A. .

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
