Which statement is true?

P(age between 25 and 35 years|hemoglobin level between 9 and 11) P(age between 25 and 35 years)

P(hemoglobin level between 9 and 11|age between 25 and 35 years) = P (hemoglobin level between 9 and 11)

P(hemoglobin level between 9 and 11|age between 25 and 35 years) = P(age between 25 and 35 years)

P(age between 25 and 35 years|hemoglobin level between 9 and 11) = P(hemoglobin level between 9 and 11|age between 25 and 35 years)

P(hemoglobin level between 9 and 11) = P(age between 25 and 35 years)..
