You are testing for a genetic condition that occurs with a 1% frequency in the population. The test has a 95% chance of being accurate (show- ing a positive result) if you have the condition, and an 80% chance of being accurate (showing a negative result) if you do not have it. (a) What is the probability that you test positive? (b) If you test positive, what is the probability that you have the condition?

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
