Answer:

0.3333 = 33.33% probability of a randomly chosen person not having cancer given that the test indicates cancer

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Test indicates cancer.

Event B: Person does not have cancer.

Probability of a test indicating cancer.

98% of 2%(those who have).

1% of 100 - 2 = 98%(those who do not have). So

$P(A) = 0.98*0.02 + 0.01*0.98 = 0.0294$

Probability of a test indicating cancer and person not having.

1% of 98%. So

$P(A \cap B) = 0.01*0.98 = 0.0098$

What is the probability of a randomly chosen person not having cancer given that the test indicates cancer?

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0098}{0.0294} = 0.3333$

0.3333 = 33.33% probability of a randomly chosen person not having cancer given that the test indicates cancer

Quadratic formulab for this

liq [111]

The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve.

Which Of The Following Expressions Denotes A Real Number? Kindly Show Your Solution.

Debora [2.8K]

Answer:

2. $\left(\frac{36}{49}\right)^{\frac{1}{2}}$

Step-by-step explanation:

1. $(-10\:000)^\frac{1}{4}$

It cannot be simplified further.

2. $\left(\frac{36}{49}\right)^{\frac{1}{2}}$

$\frac{36^{\frac{1}{2}}}{49^{\frac{1}{2}}}$

$=\frac{6}{7}$

6/7 is a real number, therefore, the answer is number 2.
