If in an experiment the probabilities of obtaining the values \(a_1 , a_2 , a_3 , a_4\) , and \(a_5\) are \(p_1 , p_2 , p_3 , p_4\) , and \(p_5\) respectively , then the expected value is defined as \(a_1p_1+a_2p_2+a_3p_3+a_4p_4+a_5p_5\). For the values and their corresponding probabilities in the table above, what is the expected value?
