You only have a one in four chance of getting the right answer for each question which is 25 percent. One fourth of 100 is 25.

Yea I was looking around on google and came up with a formula 70-30/(4-1)=60 so I was thinking 60 percent but I don't know

Odds for getting a 25%, 1 in 4
Odds for getting a 50%, 1 in 8
Odds for getting a 75%, 1 in 12
Odds for getting a 70%, 1 in 11.2, (the multiplier I used is 2.8, which is proportionally correct.)
I haven't had a probability class, but I think this is right.
