SOLUTION: The experimental probability of randomly choosing a male from a litter of puppies is 1/4. If there are 6 female puppies in the litter, how many males are there?
Let x be the number of males puppies.
Then the condition says
= .
It implies
4x = x + 6,
3x = 6
x = = 2. ANSWERCHECK. The probability is = = . ! Correct !
