Acolored chip is yellow on one side and red on the other. the chip was flipped 50 times and landed red side facing up 20 times. what is the relative frequency of the chip landing with the red side facing up?
20%
30%
40%
60%

20/50 is equal to 40/100 so the answer is 40%

Number of times red side faced up = 20

Total number of times thrown = 50

Frequency of red side = No of red side / Total    * 100%

                                      =  (20 / 50) * 100%

                                     = 0.4 * 100%

                                     = 40%

Hope this explains it.
