17% adults favor the use of unmanned drones by police agencies. Twelve U. S. adults are randomly selected. Find the probability that the number of U. S. adults who favor the use of unmanned drones by police agencies is (a) exactly three, (b) at least four, (c) less than eight

(a) P(3)=(Round to three decimal places as needed)

(b) P(x24) =(Round to three decimal places as needed.)

(c) P(x<8)=(Round to three decimal places as needed.)

Following are the solution to these question:

Step-by-step explanation:

Following are the binomial distribution with parameters:

For point a:

For point b:

For point c:

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
