In question 1,we are talking about pair of pants and shirts,a shirt can have only 1 pant.in second question a bowl can contain any no. of toys so for every toy there are 3 options,so total no. of ways=3^7
Here we multiply,because according to counting principle till an event is being completed we multiply.
