A gumball machine has different flavors sour apple,grape,orange and cherry . There are six of each flavor. $.50 are put in the m
1 answer:
Answer:
30/552
Step-by-step explanation:
In order to solve this problem you need to multiply the probability of getting grape for the first gumball with the probability of getting grape for the second gumball. Since there are 6 grape gumballs and a total of 24 gumballs (6*4). Then the probability of getting grape for the firs one is
Now there are only 5 grape gumballs available and one less in the total supply, therefore the probability of getting grape in the second try is
Finally we multiply them together to find the probability of getting two grapes in a row.

Using an exponential function, it is found that the bottle contains 255,960 atoms of tritium after 11 years.
<h3>What is an exponential function?</h3>A decaying exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem:
- The bottle initially contained 450,000 tritium atoms, hence A(0) = 450000.
- The amount decays by about 5% per year, hence r = 0.05.
Thus, the equation is given by:
After 11 years, the amount is given by:
The bottle contains 255,960 atoms of tritium after 11 years.
