Endangered Species The chart below shows the numbers of endangered and threatened species both in the United States and abroad. Endangered Threatened United States United States Foreign Foreign Mammals 63 247 10 24 Birds 88 168 15 7. Reptiles 14 63 23 16 Amphibians 6. 6. 10 4. Send data to Excel Choose one species at random. Find the probability of selecting the species for the following. Round your answer to at least three decimal places. Part: 0/3 Part 1 of 3 P (threatened and in the United States) -O Part: 1/3 Part 2 of 3 P(endangered foreign bird)
Continuous Probability Distributions
Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.
Normal Distribution
Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!
