Answer:

30%

Step-by-step explanation:

The two outcomes (can work the problem and can't work the problem) are complementary.

In probability theory, the complement of any event A is the event [not A], i.e. the event that A does not occur. The event A and its complement [not A] are mutually exclusive and exhaustive.

Complementary events are two outcomes of an event that are the only two possible outcomes.

Complementary outcomes add to 1 or 100%.

100 - 70 = 30.
