What approximate percentage of hands are winning blackjack hands? The probability is (Type an integer or a simplified fraction.)4.5.6 a How could you use a randomdigit generator or randomnumber table to simulate rain it you knew that 50% ot the time with conditions as you have today, it will rain? Choose the correct answer below. 0 A. Let the digits 1, 2, 3, 4, and 5 represent "rain," and let the digits 6, I", B, 9, and 10 represent"no rain." Generate random digits and record the results. 0 B. A randomdigit generator or randomnumber table cannot be used to simulate rain. 0 C. Let the digit 5 represent "rain," and let anyr other digit represent "no rain." Generate random digits and record the results. 0 D. Let the digits i]. 1. 2, 3, and 4 represent "rain." and let the digits 5, 6, i", 8. and 9 represent "no rain." Generate random digits and record the results. 4.5.11 Assigned Media Question Help A professional basketball star who had a reputation for being a poor free throw a. Is the proportion of successful free throws P from the simulation reasonably shooter made 5331 of the 9800 free throws that he attempted, for a success ratio close to the value of 0.544? (Hint: A proportion is said to be "reasonably close" if it of 0.544. A simulation was developed to generate random numbers between 1 and |is within the given success ratio + the probability of a single event.) 1000. An outcome of 1 through 544 was considered to be a free throw that is made, and an outcome of 545 through 1000 was considered to be a free throw that is missed. The list below shows the results for five generated numbers where O Yes, P is reasonably close to the value of 0.544. 1 represents a free throw that was made and 0 represents a free throw that was O No, P is not reasonably close to the value of 0.544. missed.
