the odds that a book will be favourable reviewed by three independent critic. a b and c are 5 to 2, 4 to 3 and 3 to 4 respectively. what is the probability none of them are in favour of the book
i think you would add 5+4+3 and 2+3+4 and divide them so 9/12 and that makes your probability which leaves a 3/12 chance non of them are in favour of the book
