You're picking out one calculator. So just divide the number of defective calculators by the total.

Surely sounds as tho' the probability of a calc. chosen at random is simply 4/50. Change that to a percentage and/or a decim. fraction.

Don't forget to fully reduce any fractions (if they want the answer as a fraction).
