The question is asking this: A wallet contains 4 bills with denominations of $1,$5,$10, and $20. You choose 2 of the 4 bills from the wallet at random and add the dollar amounts. What is the sample space? How many outcomes are there? What is the probability of getting $15? What is the probability of getting $50? What is the probability of getting at least $25??
-----------------
List the value of the combinations:
1+5=6
1+10=11
1+20=21
5+10=15
5+20=25
10+20=30
----------------
The sample space is 6,11,21,15,25,30
---------------------------------
Count the outcomes = 6
-------------------------
P(15)=1/6
P(50)=0
P(>=25)=2/6
----------
