Answer:
frequency for heads up: 0.15
frequency for tails up: 0.85
cannot
Explanation:
relative frequency formula is
![(class frequency)/(total)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/ztcx1ov9ger2h49w9zcemrglgl4syoooxm.png)
The total of the sample is 80. The class frequency for heads up = 12 , and tails up is 68
So, frequency for heads up is
= 0.15
frequency for tails up is
= 0.85
Since the probability outcomes between heads up and tails up is far, so the outcomes cannot be considered equally likely
