The total number of people at the party is the sum of the number of men and women: \[ \text{Total number of people} = 37 + 33 = 70 \] The number of women is 33. The probability of choosing a woman is the ratio of the number of women to the total number of people: \[ P(\text{woman}) = \frac{33}{70} \]
The correct option is (A) : \(\frac{33}{70}\)
There are 37 men and 33 women at a party. The total number of people is \(37 + 33 = 70\).
The probability that the prize goes to a woman is the number of women divided by the total number of people:
\(P(\text{prize goes to a woman}) = \frac{\text{number of women}}{\text{total number of people}} = \frac{33}{70}\)
