EXTREMELY URGENT a certain tennis player makes a successful first serve 72 of the time assume that each serve is independent of the others she serves the ball 6 times, what is the probability that she makes all six serves? what is the probability that she makes exactly 4 of the serves? what is the probability that she gets at least 4 of her serves in? What is the probability that she gets at most three of her serves in? What is the probability that she gets between 2 and 5, inclusive, of her serves in? How many serves, out of the 6, would you except her to make ? What is the standard deviation Of the random variable X, the number of serves she gets in? What is the probability that she gets fewer than half of her serves in or that she gets all 6 of her serves in?

"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).
