There are 76 men and 69 women in a room. 29 of the men and 23 of the women earn more than $50,000 per year.
1. what is the probability of randomly selecting a person that earns more than $50,000 per year from this group?

  52/145 ≈ 0.359 = 35.9%

Step-by-step explanation:

There are a total of 76+69 = 145 people in the room. Of them, 29+23 = 52 earn more than $50,000 per year. The probability of choosing one of those at random is 52/145 ≈ 0.35862 ≈ 35.9%.

___

For all of these probability problems, the probability of selecting an item with particular characteristics is the ratio of the number of such items to the total number of possible choices.
