Can I have answer for question 6.7,8 Thinking: Probability Due: 373 Skills; Empirical/Quantitative Skis olowing is the number of each color of M&M; found in a sample bag of 280 M&M;'s. Red Yellow Blue 30 Ora ange Green 38 Brown 63 Suppose you reach into the bag and randomly select one M&M.; Calculate the following anawers to 4 decimals. probabilities. Round your 1. P (Red) = 2, P (Yellow) = 3, P (Blue) = Suppose you reach into the sample bag and randomly select THREE M&M;'s. Calculate the following probabilities (with and without replacement). Show your calculations and round your final answers to 4 decimals. 4. The probability that the first M&M; is Red, the second M&M; is Yellow, and the third M&M; is Blue. (with replacement) 5. The probability that the first M&M; is Red, the second M&M; is Yellow, and the third M&M; is Blue. (without replacement) 6. The probability that all three M&M;'s are Blue. (with replacement) 7. The probability that all three M&M;'s are Blue. (without replacement) 8. Would it be unusual for all three M&M;'s to be blue if the sampling is done without replacement? Justify your answer using a complete sentence and proper grammar.

Explanation / Answer

6) P(all are blue) = (27/280)^3 = 0.0009 (wth replacement)

7) P(all are blue) = 27C3/280C3 = 0.0008 (without replacement

8) As the probability is less than 0.05, (0.0008 < 0.05), so it is unusual.
