What else can I help you with?
How many undecayed M and Ms would remain out of a sample of 600 M and Ms after three half lives?
75
What is the Sample space for three coins?
8
How do you find the sample space of tossing 3 coins?
You find the sample space by enumerating all of the possible outcomes. The sample space for three coins is [TTT, TTH, THT, THH, HTT, HTH, HHT, HHH].
What is the sample space for flipping a coin 3 times?
The sample space when tossing a coin three times is [HHH, HHT, HTH, HTT, THH, THT, TTH, TTT]It does not matter if you toss one coin three times or three coins one time. The outcome is the same.

After three half-lives what fraction of a radioactive sample remains?
1/8 of the original amount remains.
Why After three half-lives what fraction of a radioactive sample remains?
After three half-lives, only 1/8 (or 12.5%) of the original radioactive sample remains. This is because each half-life reduces the amount of radioactive material by half, so after three half-lives, you would have (1/2) * (1/2) * (1/2) = 1/8 of the original sample remaining.
What fraction of a radioactive sample remains after three half - life?
It is 1/8 .
What fraction of a radioactive sample remains after three half-lives?
Not sure what you mean by "had-lives". After 3 half lives, approx 1/8 would remain.
What fraction of a radioactive sample decays after three half lives?
If I take a radioactive sample of 400 moles of an unknown substance and let it decay to the point of three half-lives I would have 50 moles left of the sample. 1/2 of what is left will decay in the next half-life. At the end of that half-life I will have 25 moles left of the unknown substance or 4/25.
After three half-lives what fraction of a radioactive sample will remain?
Approx 1/8 will remain.
Sample of the three models of a fraction?
There are three models of a fraction namely area model, liner model and set model.
What fraction of a radioactive sample remains after three half lives?
Not sure what you mean by "had-lives". After 3 half lives, approx 1/8 would remain.
Is a radioactive sample has decayed until only one eighth of the original sample remains unchanged how many half lives have elapsed?
Three half lives have elapsed. This can be determined by calculating how many times the original sample size must be halved to get to one eighth: (1/2) * (1/2) * (1/2) = 1/8.
How long will it take for three-fourths of a sample of caesium-137 to decay?
It will take two half-lives or about 60.34 years for three-fourths of a Cs-137 sample to decay.
After three half lives what fraction of the daughter product has formed?
91.16% of the daughter product has formed after 3.5 half lives.
How many half-lives have elapsed when the amount of a sample's Radioactive isotopes is reduced to 3.125 percent of the original amount in the sample?
The idea is to convert the percent to a fraction (divide it by 100), and then solve the equation: (1/2)^x = (that fraction) (Note: Using "^" for "power".) In the general case, solving this equation requires logarithms. But in this specific case, you can just try out different whole numbers for "x". # 1/2 lives vs fraction 1 0.5 2 0.25 3 0.125 4 0.0625 5 0.03175 6 0.015875 The answer falls between 5 and 6 half lives, closer to 5.
