The population of voters in a hypothetical country was divided into income groups and alsoaccording to the presidential candidate they supported: a left-wing candidate, Gauche, and a right-wing candidate, Droite. Suppose the following table provides the joint probability distribution ofincome and candidate supported:Distribution of Income and Candidate15Income (X) Gauche Droite(thousandsof dollars)(Y=0) (Y=1)4075150Joint Probability250SumCandidate (Y)0.200.090.140.090.020.540.090.070.15A0.04BSum0.29с0.290.200.061What is the mean income of Gauche supporters?Enter your answer in thousands of dollars and round your answer to one decimal place. So, if youranswer is 128.47 thousands of dollars, enter 128.5 in your answer. Do not include any dollar sign.

Here given joint probability distribution of x and y X = income in thousands of dollars
