    The probability of a student to be in the orchestra or the band is 0.07 or 7%.

    Step-by-step explanation:

    The probability of a student to be in the orchestra or the band is given by the following formula:

    p (orchestra or band) = p (orchestra) + p (band) - p (orchestra and band)

    p (orchestra or band) = 0.03 + 0.05 - 0.01

    p (orchestra or band) = 0.08 - 0.01

    p (orchestra or band) = 0.07

    The probability of a student to be in the orchestra or the band is 0.07 or 7%.
