Which of the following are required for an independent random sample? Check all that apply. Every time an individual is selected
for the sample, each of the remaining individuals has a lower chance of being included. The probability of being included in the sample is the same for all members of the population of interest. The probability of being selected first for the sample is the same as the probability of being selected last. Every time an individual is selected for the sample, each of the remaining individuals has a higher chance of being included.
the probability of being included in the sample is same for all members of the population of interest. the probability of being selected first for the sample is same as the probability of being selected last

Since both trains in total weigh 360 tons and train A weighs more than train be, it means that train B is the rest of the weight when you subtract train A from the total amount. Difference means subtraction so just solve this: 360-272 to get train B and you already know that train A is 272 tons. Please mark branliest!
