- Assume that the box contains 12 markers: 8 that contain ink and 4 that do not contain ink. A sample of 7 markers is selected and a random variable YY is defined as the number of markers selected which do not have ink. Fill in the table below to complete the probability density function. Be certain to list the values of Y in ascending order.arrow_forwardLet y be the random variable with the time to hear an owl from your room's open window (in hours). Assume that the probability that you still need to wait to hear the owl after y hours is one of the following: the probability is given by 0. 47e-4y + 0. 52e-5y Find the probability that you need to wait between 2 and 4 hours to hear the owl, compute and display the probability density function graph as well as a histogram by the minute. Compute and display in the graphics the mean, variance, and quartiles of the waiting times. Please pay attention to the various units of time!arrow_forwardPlease write to text formet answer but don't copy pastearrow_forward

What is the value of c What is the probability that X is even?arrow_forwardConsider the probability density function 0 if x 4.arrow_forwardLet X be a random variable that follows the beta distribution. This random variable is continuous and is defined over the interval from 0 to 1. The probability density function is given by whereand are integers, whose values determine the shape of the probability density function. Because X varies between 0 and 1, we can think of X as the probability that some event (say) E occurs or the proportion of times an event occurs in some population. For example, E could denote the event that a critical part in a newly designed car will lead to a catastrophic failure in accidents at high speeds. The expected value (i.e., mean) of this random variable is []. That is, . The Excel commands for the beta random variable are =beta.dist(x,,,true,0,1) for the cumulative probability distribution, and =beta.dist(x,,,false,0,1) for the probability density function.
