Going fishing in a lake with bass weighing an average of 3 pounds with a standard deviation of 0.3 pounds

2 fish caught. What is the probability that both catches were 3.5 pounds or heavier?

4 fish caught with 2 of them in the lowest 20% of the weight distribution. Other 2 were in the top 10% of weight distribution. Estimate the total weight of the 4 fish = _________
