Answer:

frequency for heads up: 0.15

frequency for tails up: 0.85

cannot

Explanation:

relative frequency formula is
(class frequency)/(total)

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
(12)/(80) = 0.15

frequency for tails up is
(68)/(80) = 0.85

Since the probability outcomes between heads up and tails up is far, so the outcomes cannot be considered equally likely
