This question is about probability statistics. I would like all the workings shown and the correct answers too.

2. In the population of males over 55 years of age the probability of having high blood pressure is 0.5 and the probability of having high cholesterol is 0.3. If the conditional probability of having high blood pressure, given having high cholesterol, is 0.5, nd the joint probability of having both high blood pressure and high cholesterol. Hence, complete a table of joint and marginal probabilities as begun below. Blood Pressure Cholesterol Total 0.5 1.0 Are high blood pressure and high cholesterol independent
