Question

If a coin is flipped 10 times, how often are there 6 or more heads? A first step to answering this question would be to simulate 10 flips. Use the random number table to simulate the 10 coin flips. Let odd digits (1,3,5,7,9) represent heads, and let even digits (0,2,4,6,8) represent tails. Begin with the first digit in the third row of the random number table a. Write the sequence of 10 random digits. b. Write the sequence of 10 "heads" and "tails". Write H for heads and T for tails c. Are there 6 or more heads? How many heads are there? Click the icon to view the random number table a. Write the sequence of 10 random digits. List the numbers in order as seen in the random number table beginning with the first digit in the third row. The sequence is OOOOOOOOO

Explanation / Answer

For image - 1, the data is required so i am only attempting image - 2 and image - 3.

Image - 2:

P(Junior or neutral) = 98/277 + 39/277 - 14/277 = 123/277 = 0.444

Image - 3:

P(Exactly one down) = P(UD) + P(DU) = (0.8)(0.2) + (0.2)(0.8) = 0.16 + 0.16 = 0.32
