the bars is just the divider which creates the amount of divisions you need. E.g. there are 4 children, you need 3 dividers to divide a line into 4 spaces, hence you neeed 3 bars
It's the number of boxes, in this case, children, minus 1. If there are 4 children, there would be 3 dividers to show how many cookies each one has. ***/**/***/** - 10 cookies (*) and each divided space is a child.
1:33 Typo* It is 7 stars and 3 bars
I don't get how this works, isn't 10C_3 the subsets of 3 of the set of 10? But we want to take all of them 10 in order to get a possible scenary
wldnt the problem only be equivalent if x1, x2, x3 and x4 are all integers??
Yes
4:42 Bullet point 1: Did you actually mean that the SPACE BETWEEN the bars is the identifiable items? (Rather than the bars themselves)?
I want cookies
Ok 😂
🍪
no cookie! too much sugar
It's not good for your device
what if cookies were not identical is it make a difference ?
If they were distinguishable then you would have to multiply the solution by the number of distinct objects
How do you find the number of Bars??????
