Question

Jordan flipped a coin 218 times. Which of the following would be a good estimate of the number of times the coin landed on heads?

A. 168
B. 104
C. 209
D. 34

Answer 1

B. 104

Explanation:

It would make the most sense if it were somewhere in the middle since flipping a coin has a 50% chance of being heads.

B. 104 is closest to the absolute middle of 218, therefore, it would be the most accurate.

Answer 2

Ans: (1/2)218 = 109
