FAN & MEDAL!!!!! PLEASE HELP. Based on the tree diagram, what is the probability that the projects are in order of art, math, science? one over six two over six three over six four over six

OpenStudy (blm1):

OpenStudy (welshfella):

How many branches are there in the tree?

OpenStudy (blm1):

3

OpenStudy (welshfella):

no

OpenStudy (welshfella):

art-math science is one science - art-math is another

OpenStudy (blm1):

So 6?

OpenStudy (welshfella):

right there are a total of 6 branches and only one of those is art-math-science

OpenStudy (blm1):

So I think its 1/6

OpenStudy (welshfella):

exactly right

OpenStudy (welshfella):

suppose you were asked probability of art-math-science OR math-science-art you would ADD the probabilities this would be 1/6 + 1/6 = 1/3

OpenStudy (blm1):

Ok, thanks. Can you help with another?

OpenStudy (welshfella):

yes but please repost any more questions

OpenStudy (blm1):
