The average price of gasoline in the US is $3.73 and in Russia it is $3.40. Assume these averages are the population means in the two countries and the probability distribution are normally distributed with a standard deviation of $.25 in the US and the standard deviation of $.20 in Russia. Show your work.a. What is the probability that a randomly selected gas station in the US charges less than $3.50 per gallon? b. What percentage of gas stations in Russia charge less than $3.50 per gallon? c. What is the probability that a random selected gas station in Russia charges more than the mean price in the US
