When I go to work, there's a 20% probability that I'll forget my office keys and a 30% probability that I'll forget my wallet. If there's a 8% probability that I forget both, then what's the probability that I arrive at work with both my office keys and my wallet?

Enter your answer as a percentage.

The probability that you forget your office keys or your wallet is 20 + 30 - 8 = 42%.

So now we subtract 42% from 100%.

58% is the answer. Hope this helps.
