Suppose, a transportation company conducted a study to consider demand level of their transportation systems during the rush hour for 180 days and for this purpose, the following table was constructed to represent the results. Transportation Systems Demand Level Total Y Low A 22 Medium 42 C 92 High E 46 Total 94 180 a. What is the probability of using transportation system X during the rush hour? Answer in exact fraction, or rounded to at least 4 decimal places b. What is the probability of using transportation system Y during the rush hour? Answer in exact fraction, or rounded to at least 4 decimal places c. What is the probability of using transportation system X when the demand level was high during the rush hour? Answer in exact fraction, or rounded to at least 4 decimal places d. What is the probability of using transportation system Y when the demand level was medium during the rush hour? Answer in exact fraction, or rounded to at least 4 decimal places
