Approx. 61%

Step-by-step explanation:

There's 38 faculty members in total. 23 of them are either professors or instructors (I just added 11 and 12).

So 23/38 members are one of the two. In terms of percentage (which can be found by dividing 23 by 38 and multiplying by 100), you have about a 61% chance.
