Help me please this subject is mathematics. Darius is gardening and has 20 pounds of potting soil. He uses 11.85 pounds in one flower bed. How much does he have left to use for the remainder of his yard?

Plz me i need i will give a brain

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)

Can someone check if i did this correct. it’s number 4 if you’re wondering.
