A Gallup Poll in March 2007 asked 1005 adults whether increasing domestic energy production or protecting the environment should be given higher priority. Here are the results:

Response                                      Number
Increase Production.............................342
Protect the Environment.....................583
Equally Important..................................50
No Opinion..............................................30
Total.....................................................1005

If we select a person at random from this sample of 1005 adults,

a) What is the probability that the person responded “Increase Production”?

b) What is the probability that the person responded “Equally Important” or had “No Opinion”?
