All right, in the experiment we've got seven red apples and four yellow apples to give us a sample space of 11 apples.
00:16
Now we want to find a probability that there are more red apples than yellow apples.
00:23
So meaning to say we may have zero red apple, in which case we will have red, red, red, red, red, red, or we can have two red and one yellow.
00:52
So those are the two cases that we can work quick.
00:57
Now this one will have rr which is 7 over 11 times 6 over 10 times 5 over or so we add red seven over eleven times another red six over eleven times yellow four over nine so these two red and one yellow have got three possibilities so we're not applied by three but each possibility is just the same as the other one in terms of the so just get one property, then we multiply it by three.
01:58
So this is equal to 5 into 5, 1, 5 into 10, 2, 3 into 6, 2, 3 into 9, 3 into 9, 3...
