In the game of tic tac toe, if all moves are performed randomly the probability that the game will end in a draw is 0.127. Suppose six random games of tic tac toe are played. What is the probability that at least one of them will end in a draw.

Assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1. Draw a graph and find the bone density test scores that can be used as cutoff values separating the lowest 10% and highest 10%, indicating levels that are too low or too high, respectively. Sketch the region containing the lowest 10% and highest 10%. Choose the correct graph below. OA. -Za Za Q The bone density scores are ☐ OB. -Za Za (Use a comma to separate answers as needed. Round to two decimal places as needed.) ○ C. Q Za -Za D. Q a G Za -Za

The​ least-squares regression equation is y=761.7x+13,208 where y is the median income and x is the percentage of 25 years and older with at least a​ bachelor's degree in the region. The scatter diagram indicates a linear relation between the two variables with a correlation coefficient of 0.7483.   Predict the median income of a region in which 20​% of adults 25 years and older have at least a​ bachelor's degree.

Emily rolls a pair of standard dice. What is the probability that she gets a sum of 8 or at least one of the dice shows a 3?
