Ateacher dropped 8 coins on the table and counted the number of tails to simulate the number of questions a student might guess correctly on a true/false quiz with 8 questions. the dot plot below shows the results of one hundred trials. based on this data, which number of correct answers is most unlikely? a dot plot labeled 0, 1, 2, 3, 4, 5, 6, 7, 8 along the bottom. above the zero is 4 dots. above the 1 is 13 dots. above the 2 is 12 dots. above the 3 is 10 dots. above the 4 is 8 dots. above the 5 is 4 dots. above the 6 is 17 dots. above the 7 is 15 dots. above the 8 is 12 dots.

Get 0 tails (correct answers in the test)

Get 5 tails (correct answers in the test)

Step-by-step explanation:

This is a problem of empirical probability calculation, since the teacher tries to find by means of the experimental method, the number of correct answers that a student could correctly guess in a true / false test with 8 questions.

If the teacher throws the 8 coins and then counts the number of tails, the graph shows the frequency with which 1, 2, 3, 4, 5, 6, 7 and 8 tails are obtained in the 100 attempts.

Therefore, the least probable result was the one that was obtained less frequently in the experiment or, in other words, the one that contains fewer points in the diagram, which in this case are:

Get 0 tails (correct answers in the test)

Get 5 tails (correct answers in the test)

Step-by-step explanation:

The marginal totals are the sum of each row and column.

For example, the total number of sophomores is 120 + 302 = 422.
