Question

A colored chip is yellow on one side and red on the other. The chip was flipped 50 times and landed red side facing up 21 times. What is the relative frequency of the chip landing with the red side facing up?
42%
58%
68%
72%

Answer 1

42%

You have essentially a fraction, 21/50, which gives you a decimal of 0.42, or 42%.

(Flipped a total of 50 times, of those, it landed red side up 21 times, so 21/50)
