Suppose 30% of Ontarian adults oppose the cancellation of the cap-and-trade plan for reducing carbon emissions. A random sample of 10 Ontarian adults is selected. Assuming independence, use the binomial formula to answer the following questions.

Round your final answers to 4 decimal places and express answers in decimal form (i.e. 0.0003 instead of 0.0300%)

(a) What is the probability that at most 2 of those selected oppose cancelling the plan?

(b) What is the probability that at least 1 Ontarian adult selected opposes cancelling the plan?

(c) What is the probability that exactly 8 of the 10 selectedsupportcancelling the plan?

(d) How many Ontarian adults would you randomly select if you expect to find 165 adults who oppose cancelling the cap-and-trade plan?

For part (e), round your answer to 2 decimal places.
