Question

Jason and Jessica spin a penny 80 times and record the results in this table. Heads up 12 tails up 68 .the relative frequency of heads up is ______ .the relative frequency of landing tails up is ______.the two outcomes ______be considered equally likely.

Answer 1

12/80= 0.15

68/80= 0.85

Cannot

Explanation:

Answer 2

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
