    Say the chance was 80% (it probably isn't). That means the chance he was accepted to NONE of the schools is 20%. So we want to solve for the chances he wasn't accepted anywhere and then figure out the chances he got at least 1 acceptance.

    P(no acceptance) = 55% * 65% * 30% * 44% (these are the percentages obtained when you do (100 - x) to all four percentages above - they represent the percentage of not getting accepted after an interview)

    P(no acceptance) = (0.55)(0.65)(0.30)(0.44) = 0.04719
    P(no acceptance) = 4.719%
    P(acceptance somewhere) = 100 - 4.719 = 95.381%
