Could someone check my problems for me?

I was wondering if someone could check my problems for me. I'd really appreciate it. I'm new at statistics so if I'm way off don't hesitate to laugh. (Giggle)

1)Two 6-sided dice are rolled. What is the probability that the sum of the two numbers on the dice will be 5?

2)A bag contains 2 red marbles, 3 blue marbles, and 7 green marbles. If a marble is randomly selected from the bag, what is the probability that it is blue?

3)A class consists of 41 women and 74 men. If a student is randomly selected, what is the probability that the student is a woman?

4)A survey resulted in the sample data in the given table. If one of the survey respondents is randomly selected, find the probability of getting someone who lives in a flat. Round to the nearest thousandth, if necessary.

Type of

accommodation | Number

------------------------

House | 258

Flat | 518

Apartment | 406

Other | 426

5)Use the relative frequency approach to estimate the probability of the event.

The data set represents the income levels of the members of a country club. Estimate the probability that a randomly selected member earns at least $88,000

96,000 104,000 86,000 108,000 87,000 96,000 88,000 84,000 116,000 136,000 85,000 92,000 112,000 87,000 104,000 100,000 88,000 120,000 83,000 100,000

My anwsers are this

1).111

2).250

3).357

4).322

5).700 or 70%

Thanks for any help.
