How will I solve a question contain three different things

[Prasen]

I had a doubt. I thought it was probability distribution for choosing 2 red balls simultaneously. The question didn't precise it but the teacher started doing for successive picking 2 balls at 4:12 he mentioned "simultaneously".

exactly what I needed for my school work. thank you!

[jaredtay]

Is there any more efficient way to calculate because as it takes more turns more time and effort needed to find probability.

[sumedhganpatye]

What if we took out two green balls or two red balls at the first time only ???
