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%.
Since you're adding on to the regular price, you can say it is 125% of the price. Or you can use the regular equation:
Since you're only finding 25% of 24.5, you have to add on 24.5 because you're paying for the beach towel and applying the sales tax.
Now, since cents are to the hundredths place, you have to round.
The final price would be $30.63
