Three different cars are available to take 4 men and 1 woman on a particular journey. In how many different ways can the five people be allocated to the cars so that the woman is alone?

1. 2 men, 2 men, woman

2. 3 men, 1 man, woman

3. 4 men, woman

So 3

There does not seem to be enough details but you i would say these are a few:

Car1-Woman, Car2-one man, Car3 - 3 men

Car1 - 2 men, Car2 - 2 men, car3 - woman

Car1 - none, Car2 - 4 men, car3 - woman

You will have 3 in total
