Suppose you roll two dice. Let X represent the number of even numbers appearing on the dice.For instance:- (1 & 3) is X=0 even numbers.- (2 & 5) is X=1 even number.- (4 & 4) is X=2 even numbers.| X | P(X=x) ||---|--------|| 0 | || 1 | || 2 | |Give probabilities as decimals or fractions (not percents).

A recent survey by the New Statesman on British social attitudes asked respondents if they believe that inequality is too large. The survey found that 65% of the respondents do believe inequality is too large. In a sample of six British citizens, what is the probability that two believe inequality is too large? If required, round your answer to four decimal places.f (2) = In a sample of six British citizens, what is the probability that at least two respondents believe that inequality is too large?
