Worked solution
Probability = favourable count ÷ total count (not ÷ the rest — that's odds). The correct answer is 38.7%. Traps to avoid: 25.8% comes from the "wrong category" error; 35.5% comes from the "wrong category" error; 32.4% comes from the "wrong total" error; 63.2% comes from the "odds not probability" error.
