    975 bulbs

    Step-by-step explanation:

    1/40 bulbs were defective

    That means 1-1/40 were not defective

    40/40 - 1/40 = 39/40 were not defective

    We have 1000 bulbs

    Multiply the number of bulbs by the fraction that is not defective to get the number of bulbs that should not be defective.

    1000 * 39/40 = 975 bulbs
