We need P(positive | vaccinated) = (number vaccinated who tested positive) ÷ (total number vaccinated).
You gave the numerator 465, but not the table's vaccinated total. From your choices:
- 465/2321 ≈ 0.200
- 465/1236 ≈ 0.376
- 465/950 ≈ 0.489
- 465/485 ≈ 0.958 (impossible — probability > 1, so this one can be ruled out)
Pick the fraction whose denominator equals the total number of vaccinated people in the two‑way table (vaccinated positive + vaccinated negative). If you post the table or the total vaccinated, I’ll give the final fraction and decimal.
