The u. s. national highway traffic safety administration gathers data concerning the causes of highway crashes where at least one fatality has occurred. from the 1998 annual study, the following probabilities were determined (bac is blood-alcohol level): p(bac=0|crash with fatality)=0.646 p(bac=0|crash with fatality)=0.646 p(bac is between .01 and .09|crash with fatality)=0.322 p(bac is between .01 and .09|crash with fatality)=0.322 p(bac is greater than .09|crash with fatality)=0.032 p(bac is greater than .09|crash with fatality)=0.032 suppose over a certain stretch of highway during a 1-year period, the probability of being involved in a crash that results in at least one fatality is 0.027. it has been estimated that 15% of all drivers drive while their bac is grater than .09. determine the probability of a crash with at least one fatality if a driver drives while legally intoxicated (bac greater than 0.09).

Of four points are collinear, they are also coplanar

Arestaurant gives out a scratch-off card to every customer. the probability that a customer will win a prize from a scratch-off card is 25%. design and conduct a simulation using random numbers to find the experimental probability that a customer will need more than 3 cards in order to win a prize. justify the model for your simulation, and conduct at least 10 trials.

The table shows the relationship between the number of cups of cereal and the number of cups of raisins in a cereal bar recipe: number of cups of cereal number of cups of raisins 8 2 12 3 16 4 molly plotted an equivalent ratio as shown on the grid below: a graph is shown. the title of the graph is cereal bars. the horizontal axis label is cereal in cups. the x-axis values are 0, 20, 40, 60, 80,100. the vertical axis label is raisins in cups. the y-axis values are 0, 10, 20, 30, 40, 50. a point is plotted on the ordered pair 40,20. which of these explains why the point molly plotted is incorrect? (a) if the number of cups of cereal is 40, then the number of cups of raisins will be10. (b)if the number of cups of raisins is 40, then the number of cups of cereal will be10. (c) if the number of cups of cereal is 40, then the number of cups of raisins will be 80. (d) if the number of cups of raisins is 40, then the number of cups of cereal will be 80.
