Probability of compound events: picking a number from 1 to 5 and choosing the color red, white, orblue

1 in 15, or 6,67%

Step-by-step explanation:

We'll suppose a few things here, because your question isn't very explicit on details.

First, we'll suppose the numbers and the colors are placed in two different bags/bowls.. so you do one pick for a number and one pick for a color, since you talk about compound events.

Second, the question says "picking a number" and "choosing the color...".  We'll assume it means chances of picking a specific number and a specific color... like "Number 3 and color white".

Since they are compound events, you multiply the probability of each one occurring.

First, how many chances to pick a given number from the 5 numbers?

1/5 right?

How many chances to pick a given color from the 3 colors?

1/3 right?

Every time you pick the number 4, you still have 3 possibilities regarding the color.

So, the compound probability is:

1/15 to pick a specific number/color combination.

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
