There are 12 numbers in total. There is a 2 on each cube so there are two possible chance. 2/12=1/6 2/2=1 and 12/2=6 therefore 2/12=1/6
The probability that a patient with a negative result is truly HIV-free is 0.999.
<h3>How to find the probability that the negative result is correct?</h3>
To find the probability that confirms that the result of the HIV test is negative, we must take into account the information provided in the information and perform the following mathematical operation.
The probability that No HIV and test positive is:
P = 0.85 * 0.985
P = 0.8372
The probability that HIV and test negative is:
P = 0.15 * 0.003
P = 0.00045
The probability that No HIV and negative test of HIV and negative test is:
P = 0.00045 + 0.8372
P = 0.8377
P = (NOT HIV / Test)
P = 0.8372 / 0.8377
P = 0.999
According to the above, the probability that a patient with a negative result is truly HIV-free is 0.999.

The answer is 50
X represents a toaster, x-20 represents a rice cooker
Use the equation 5x+3(x-20)=500
Solve for x and get 70.
A toaster is 70 but a rice cooker is 50
