If there are 6 cats and 7 dogs and 4 of them are chosen out of all 13 you have a 50 percent chance out of all 4 chosen animals that 2 of thwm are cats because 4 animals divided by 2 cats equals 2 which on percentage scale is 50 percent

anonymous · Answer

Thw probability that at least 1 cat was miraculously choswn in the group is 25 percent because 4 animals divided by a probability of 1 cat equals 1 and on the percent scale of 100 1 out of 4 equals 25 percent

So 50 percent or 1 halve
25 percent or 1 fourth
