Answer:
Step-by-step explanation:
one tenth is 1/10 these are the coins from Europe (0.1)
32/100 is the coins from Asia (0.32)
You add these together to get 42 hundredths or 42/100 (0.42)
42/100 is equal to 0.42.
Answer:
a) 74.69
b) 0.08% probability that on a given day, 51 radioactive atoms decayed.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
a. Find the mean number of radioactive atoms that decayed in a day.
27,263 atoms in 365 days. The mean is
b. Find the probability that on a given day, 51 radioactive atoms decayed.
This is P(X = 51).
0.08% probability that on a given day, 51 radioactive atoms decayed.
