Bro is using the grade 12 teacher method and I don’t understand anything😅
@maryannlina4954
for people who don't understand so its 2 pink is equal to 5\10 because there are 5 pink and the total is 10 and you will subtract 1 from 5 and 10 is equal to 4\9 you will multiply 5\10 and 4\9 which equals to 2\9 and subtract 1 equals 2\9 because if we subtract that we might simplify or do it in fraction . Am i right? i wont beg for you to like my comment.
@Franklin-go3lw
Why are you subtracting from one
@AbdulmuminYahaya-l2e
This doesn't make sense

It's selection of 2 marble so it a question of combination it must be 1- 5C2/10C2

This is how you find the right answer, E/N E=event(the said event that we are looking for) N=Sample Space(total number of possible outcomes) We solve for N since it's easier, 5 green and 5 pink will be N = (5*5) = 25 E/25 For event, we need to find how many are both pink which will be (pink*(pink-1)) = (5*4) = 20 but in this case we divide by 2 as; [If you dont, then cases like (pink1, pink2) and (pink2, pink1), which is basically the same, so therefore we must divide by 2],by that logic BothPink = (pink*(pink-1))/2 = (5*4)/2 = 20/2 = 10, Since we are finding for NOT both pinks we subtract this for the sample space, E = 25-10 = 15 E = 15 N = 25 E/N = 20/25 = 2/5 2/5 is the right answer for this
