Legacy chances for Miami?

So I’ve been thinking of applying to University of Miami (FL). I have a pretty weak profile, but I’ll be applying as a legacy applicant because my grandpa graduated from Miami.

W GPA: 3.56
UW GPA: 3.4
ACT: 28
150 hrs of community service at a food bank, went on a mission trip to Costa Rica last summer, key club for 3 years, robotics club for 2 years, Spanish National Honors Society for 2 years (president this year), engineering club for a year, and basketball freshman year.

Anyone have an idea of what my odds would be? Thanks in advance!!

Also I’m white, an Illinois resident, and have worked as a cashier at jewel osco for a year (12-20 hours/week) and a country club (still employed, ~20-25 hours a week)

they love legacies, my current roommate at UM had a 3.4 GPA and an act of 28, her mom went to UM only for a year and they aren’t donors or anything. good luck!!!
