Answer:
The probability that the pet seen was sick is 53.57%.
Step-by-step explanation:
The probability of an event <em>E</em> is the ration of the number of favorable outcomes to the total number of outcomes.
Here,
n (E) = number of favorable outcomes
N = total number of outcomes
Denote the events as follows:
<em>C</em> = the pet is a cat
<em>D</em> = the pet is a dog
<em>O </em>=<em> </em>the pet is some other animal
<em>S</em> = the pet is sick.
The data provided is summarized as follows:
n (C) = 28
n (C ∩ S) = 3
n (D) = 42
n (B ∩ S) = 4
n (O) = 24
n (O ∩ S) = 8
Compute the probability that a cat was sick as follows:
Compute the probability that a dog was sick as follows:
Compute the probability that another animal was sick as follows:
Compute the probability that the pet seen was sick as follows:
P (S) = P (C ∩ S) + P (D ∩ S) + P (O ∩ S)
Thus, the probability that the pet seen was sick is 53.57%.
Modulo - The result of multiplying the original number by three and the result of multiplying the digits by three must be the same.
What is modulo?
In mathematics, the phrase modulo, which literally means "with respect to a modulus of," is frequently used to claim that two different mathematical objects can be regarded as comparable if their difference is explained by a third component.
Using the Fermat's little theorem:
when x=10. You may easily establish the identity by multiplying it term by word. All terms cancel, excluding the first and last ones. Therefore, any power of ten minus one is divisible by nine, and consequently, by three
Now consider a multi-digit natural number, 43617 for example.
Other than the sum of the digits, every term on the right is divisible by 3. The result of multiplying the original number by three and the result of multiplying the digits by three must be the same.
