A landscaping company claims that 90 of the trees they plant survive (defined as being still alive one year from planting). If a tree does not survive, the company will replace the tree with a new one. A homeowner will have 5 trees planted in his yard by this landscaping company. Consider these 5 trees to be a random sample of all trees planted by this company. If the company's claim is correct, what is the probability that all 5 of the trees will survive?
 a. (0.1)5
  b. (0.9)5
  c. (0.1) + (0.1) + (0.1) + (0.1) + (0.1) = 0.5
  d. (0.9)
