Suppose a poll of 1066 adults asked how to deal with an energy shortage: use more production, more conservation, or both? Suppose 3 people are selected at random from this sample

More Production: 415
More Conservation: 572
Both: 55
No Opinion: 24
Total: 1066

a) What is the probability that all three responded "More conservation"?
(Round to three decimal places as needed.)
b) What is the probability that none responded "Both"?
(Round to three decimal places as needed.)
c) What assumption must be made to compute these probabilities?
A. The events are independent. B. The events occur simultaneously. C. The order of the events does not matter. D. The events are disjoint.

Someone answer this asap rn for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
