It is given that:
Santos flipped a coin 500 times. The coin landed heads up 225 times.
The number of heads = 225
The number of times coin flips = 500
The ratio of heads to a total number of coin flips:
= 225/500
Divide by 25 on the numerator and denominator, we get:
= 9/20
The ratio = 9:20
Or
9 to 20
Thus, the ratio of heads to the total number of coin flips is 9:20 option (D) 9 to 20 is correct.
