A Gallup Poll (www.gallup.com/poll/161729/americans-divided-energy-environment-trade-off.aspx) in March 2013 asked 529 U.S. adults whether increasing oil, gas, and coal production or developing alternative energy sources such as wind and solar power should be given a higher priority. Here are the results:
Response Number
Oil, gas, coal ……………..164
Wind and solar …………..312
Equally Important ……….. 37
No Opinion ……………… 16
Total ……………………..529
If we select a person at random from this sample of 529 adults,
a) What is the probability that the person responded "Increase oil, gas, and coal"?
b) What is the probability that the person responded "Equally important" or had no opinion?
