Please let me know the answer and answer to (a)(b)(c)(d). Q. The advertisement content of the electronic display advertisement changes after a certain period of time. The table on the right shows the distribution of the change time (measured by day) of the advertisement content.

Time required to change l Probability1.5 days. 0.153.0 days. 0.254.5 days. 0.305.0 days. 0.207.0 days. 0.10(a) James sees this table and says, "The contents must change after at least a week." Explain how James can make this argument.(b) Find the probability that any advertising change will occur within four days. If there have been 10 changes in advertising during observation for more than a month,(c) find the probability that at least one change in 10 changes occurred within 4 days. At this point, elaborate on how the probability variable x is defined.(d) Find the average value of the number of changes that would have occurred within 4 days of 10 changes.
