5. The school cafeteria offers vanilla swirl and chocolate ice cream, with and without fudge sauce on Fridays. The cafeteria manager kept a record of the 150 students who ordered ice cream on Friday to prepare for the next
weeks' order of ice cream. Use the information in the table to find the following probabilities for a randomly
chosen ice cream order.

a. Find the probability that an order will include fudge sauce.
b. Find the probability that the order will include fudge sauce given that it is for vanilla swirl ice cream.
c. Find the probability that an order will be for vanilla swirl ice cream, given that it will not include fudge sauce.

1/800 is the right answer

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

"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).
