Answer:
8
Step-by-step explanation:
Hello,
Answer D:
the roots are -5,1+4i,1-4i,-4i,4i.
The theoretical probability of getting heads or tails is 1/2 the time.
1/2 of 150 = 75
So theoretically you would get 75 heads and 75 tails.
The experiment got 84 heads, which is greater than 75, so it would be higher than the theoretical probability.
The answer is : <span>It is 6% higher than the theoretical probability.</span>
