That's the calc for the first one. But in the second case you already know the first is red. So it's only 5/35
If you pick the first orange out and put it aside it takes one candy out of the basket, making there be 5 oranges and 30 yellows, 30+5=35.
Therefore the probability of you getting orange again is 5/35, or 1/7.
(6/36)*(5/35)
and i'm not sure how is the other one meant. either it's the same or it's 5/35 since you're choosing only from 5 orange in 35 sweets
unless i'm missing on something.. i'm not really good at combinatorics, this stuff is quite boring.
its the same thing. It will be 6/36 * 5/35. Doesn't matter if they're picked together or simultaneously
What YAN did is technically the correct way of doing it, but the value in the end is the same anyway.
If you look at the first one and see it is orange. Then the chance if the second one also being orenge is 5/35.
Not sure if that's what you meant.
If you put the first one back before picking the second, it's 1/36 chance overall. If you leave the first one out before picking the second, it's 1/42 chance.
The possibility of ur goal is (number of oranges/total) . U want "only and only 2 oranges instant",when u go.So the possibilities are multiplied.
p1*p2.
1st case and 2nd are the same in fact. p1= 6/36 * p2=5/35;

If there are 36 sweets in a basket, 6 of it is orange and the rest is yellow. You are blind folded. What are the chances of u picking 2 orange at one go.
Is the answer same as u pick the first sweet and u look at it, it was orange, u put it aside, and u pick the second one turn out it is orange too???
