How many outcomes are there in the following events/experiments?

Question

1. Getting a 1.50 from a purse with 1.00 coins and 25 cents coins

2. Getting from A to B by moving Right and Down along a grid only

Answer 1

If you are removing 3 coins and seeing if you get 1.50, there are 4 outcomes:
1 .25 + .25 + 1.00 = 1.50
2 .25 + .25 + .25 = .75
3 .25 + 1.00 + 1.00 = 2.25
4 1.00 + 1.00 + 1.00 = 3.00
