What is the expected value of attempting a field goal?

Hello everyone!
I'm confused because 90% and 35% obviously do not add up to 100%
and as a result I'm really flustered! :C I appreciate the help and efforts of everyone on this website! :D

Hi Coder74!

Indeed, those do not add up to 100%.
I can only assume we have 90% chance to score a field goal and 10% chance to score nothing at all.
... unless we set our objective to a touchdown...

The question is "find the expected value of a field goal" (I would have said "the expected value of attempting a field goal") which means the probability of a touch down is irrelevant. A field goal has value 3 points and the probability of success is 0.9 so the "expected value" of attempting a field goal is (3)(0.9)= 2.7 points.
