3/38Incorrect.

Answer 1

6/20 * 6/20 = 36/400 = 9/100

It is really not that hard, but you missed a important word on your question if the red marbles are taken out or put back in

Answer 2

Answer:

$: \implies \bf \dfrac{9}{10}$

Step-by-step explanation:

Given :

A bag contains :

• 6 Red marbles.
• 4 Blue marbles.
• 10 Green marbles.

Two marbles are drawn, with replacement.

To Find :

The probability of drawing Two Red marbles is a row.

Solution :

• Let's find the total quantity of Marbles.

⇒  6 + 4+ 10

⇒ 20.

So,

$\implies \sf \dfrac{6}{20}\times\dfrac{6}{20}\\ \\ \\\implies \sf \dfrac{36}{400}\\ \\ \\\implies \bf \dfrac{9}{10}$
