John and Ann run an animal shelter that houses cats and dogs. The ratio of cats to dogs is 5:4. Of the cats, 2/5 are kittens, while 3/7 of the dogs are puppies. The shelter houses a total of 63 animals. A group of 6 animals is chosen at random from the shelter. What is the probability that the group contains at least one kitten? Give your answer to 4 decimal places.
 
Can you show us what steps you've already done and what work you've tried? Even if you know you have the wrong answer, showing us what you've tried will help us be able to help you. Remember, the name of the site is "Free Math Help," not "We'll do your homework for you."

In case you're completely stuck on this problem, I'd recommend starting by figuring out how to write c (how many cats) as a multiple of d (how many dogs), so that you know how many of the 63 animals are cats and thus how many kittens there are.
