I'm having a hard time figuring this out and setting it up. I get really confused with symbols and how to write the problems out.

Ok a football team needs to score 23 points in three plays. Assuming they're definitely scoring 3 touchdowns they still need 5 points. A field goal has a probability of 82% success rate. A 2 point conversion 18% probability of success.

Is it better to go for three 2 point or Two 2 point conversions and one field goal and whether they should start with the fg followed by two 2pt conversions or 2 pt conversions first and then a fg.
