~Hello There!~

First find out the total number of marbles:

In this case it is 10

Keep this number in mind as it will be the denominator

The probability of getting a pink the first time would be:

[tex]\frac{3}{10}[/tex]

Since it is replacement, there would still be 3 pink marbles for the second draw so this fraction would also be [tex]\frac{3}{10}[/tex]

You would need to multiply these results together to get the final result:

[tex]\frac{3}{10} *\frac{3}{10}[/tex]

Doing this would give you an answer of:

[tex]\frac{9}{100}[/tex]

Hope This Helps You!

Good Luck :)

Have A Great Day ^_^

The probability of drawing two pink marbles if the first one is placed back in the bag before the second draw is 0.3.

Probability

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

Given

Total 10 balls are there.

The 3 balls are pink, 2 balls yellow, and 5 balls are blue.

To find

The probability of drawing two pink marbles if the first one is placed back in the bag before the second draw.

How to get probability?

We know the formula

[tex]\rm Probability = \dfrac{Favorable\ event}{Total\ event}[/tex]

Then probability will be

[tex]\rm Probability = \dfrac{3}{10}\\\\Probability = 0.3[/tex]

The probability of drawing two pink marbles if the first one is placed back in the bag before the second draw is 0.3.
