The percentage of the original sample that is left after 115 days is; 23.4733%
<h3>How to calculate the decay percentage?</h3>
Formula for radioactive decay is;
A = A₀ * (1/2)^(t/t_¹/₂)
where;
A = quantity of the substance remaining
A₀ = initial quantity of the substance
t = time elapsed
t_¹/₂ = half life of the substance
Thus;
A/A₀ = (1/2)^(115/55)
A/A₀ = 0.234733 or 23.4733%

Answer:
3/16
Step-by-step explanation:
1. The number of spaces that are red is three and the total is 8, so the probablility of red is 3/8
2. The probability of tails is 1/2
3. multiply the expressions 1/2 x 3/8 = 3/16
