I need help with some statistics

answers with some explanation would be helpful

  1. Suppose now that the weights of coconuts from a plantation are normally distributed with a mean of 3 lb and a standard deviation of 1 lb. If we select a coconut randomly, what is the probability of the coconut weighing less than 2.5 lb?
  2. The weights of coconuts from a plantation are normally distributed with a mean of 3 lb and a standard deviation of 1 lb. If we select a coconut randomly, what is the probability of the coconut weighing between 2.5 lb and 3.5 lb?
  3. The weights of coconuts from a plantation are normally distributed with a mean of 3 lb and a standard deviation of 1 lb. What is the weight of a coconut in the 95th percentile? That is, find the weight such that 95% of coconuts weigh less (or 5% of coconuts weigh more).
