A diamond can be classified as either gem dash quality or industrial dash grade. Suppose that 89% of diamonds are classified as industrial dash grade.

(a) Two diamonds are chosen at random. What is the probability that both diamonds are industrial dash grade?
(b) Five diamonds are chosen at random. What is the probability that all five diamonds are industrial dash grade?
(c) What is the probability that at least one of five randomly selected diamonds is gem dash quality? Would it be unusual that at least one of five randomly selected diamonds is gem dash quality?

Would it be unusual that at least one of five randomly selected diamonds is gem dash qualitygem-quality?

step-by-step explanation:

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
