Probability
In the election, 2400000 voters out of a total of 6000000 voters voted for party Z. Let us randomly select three voters and consider the random variable ξ={number of voters of party Z in the sample of three voters}. Determine
a) the probability distribution, the distribution function F(x) and P(0.8< ξ <3.7),
b) the standard deviation of the random variable ξ.
