3. Let X be distributed as a geometric with a probability of success of 0.15.a. Give a truncated histogram (obviously you cannot put the whole sample space on the x-axis of thehistogram) of this random variable.b. Give F(x)c. Find the probability it takes 10 or more trials to get the first success.d. Here is a challenge. What is the probability that it takes an even number of trials to get the firstsuccess, i.e., P(X=2,4,6,8,...)

Each of the boxplots shown summarizes 24 student scores on a recent test in two different classes. The boxplots are drawn using a common numerical scale. Which of the following must be true? 1. The lower 25% of Class B are much more spread out than the lower 25% of Class A 2. More people scored below the lower quartile for Class A than Class B 3. The distribution for Class B is skewed left and has a noticeable outlier as well, while the distribution for Class A is somewhat skewed right 4.Class A had more people between the median and the lower quartile than Class B. 3.The distribution for Class A is somewhat symmetric, while the distribution for Class B is skewed right with a noticeable outlier as well
