QUESTION 4 Reconsider the previous probability of randomly selecting a stock from the portfolio that closed higher in recent trading, expressed horizontally as 5/8. Now, report it as a terminating percentage; do not round the answer, but yes, include the percent symbol, in this format: ##.#%
QUESTION 6 Return to the closing stock prices per share for eight recently traded stocks from a portfolio, with five closing higher and the others did not. What is the probability a randomly selected stock from this portfolio did not close higher in recent trading? Again, express the answer as a fraction, written horizontally: #/# QUESTION 7 Now express this complementary probability for the chance a stock did not close higher as a percentage, without rounding but include the percent symbol.
QUESTION 10 When you add the complementary percentages together, what percentage do you get? Report it with the percent symbol without any insignificant digits. Keep in mind this will be true in every case like it!
QUESTION 12 Now, continuing with this example with closing stock prices example when five stocks closed higher and one stock closed unchanged in the portfolio of eight stocks after recent trading, determine that probability for randomly selecting a stock that closed either higher or unchanged after recent trading. Express the answer as a percentage, including percent symbol but without insignificant digits. QUESTION 13 How did you compute the previous answer for the probability of randomly selecting a stock from a portfolio that either closed higher or closed unchanged after recent trading? What did you do with the individual or simple probabilities for stocks that closed higher and stocks that closed unchanged? Describe your arithmetic operation in a single, three-letter word. Two words could work that are associated with an arithmetic operation that is not subtraction, multiplication or division. Now you got it? Report only one of the two words, your choice, all lower case letters. You got this!
QUESTION 15 0 Therefore, continuing with this example with closing stock prices example when five stocks closed higher and one stock closed unchanged in the portfolio of eight stocks after recent trading, determine that probability for randomly selecting a stock that closed neither higher nor unchanged after recent trading. Express the answer as a percentage, including percent symbol but without insignificant digits.
