Ten tiles numbered 1 through 10 are placed in a bag. you randomly choose one tile. without replacing the first tile, you randomly choose a second tile. find the probability of choosing the 4 and then a number less than 5. write your answer as a fraction in simplest form.

answer: answer

step-by-step explanation:

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
