Based on the tree diagram below, what is the probability that a student doesn't have lice, given that the student tested negativ

oee [108]

Answer:

Option D (APEX)

Step-by-step explanation:

L= Student has lice

NL= Student has no lice

PT=Test Shows positive

NT=Test Shows negative

P( $\frac{NT}{NL}$ ) =0.7708 (Probability that a student has no lice and the test shows negative)

P( $\frac{NT}{L}$ ) = 0.0108 ( Probability that a student has lice and the test shows negative)

$P\frac{NT}{NL}$ = $\frac{P\frac{NT}{NL} }{P\frac{NT}{NL} +P\frac{NT}{L} }$
$\frac{0.7708}{0.7708+00108}$
$\frac{0.7708}{0.7816}$
0.98618219 (Simplify)

Terms Of Percentages

0.98618219 × 100

=98.6

Therefore your answer is 98.6% (Option D)

The inequality is a > 12, which means a is greater than 12. This means that we are looking for numbers that are greater than 12 to place into the solution set. Options A and B are incorrect because 10 and 11 are both numbers less than 12, respectively. Option D is also incorrect because the inequality specifies that the numbers in the solution must be greater than 12, not equal to it, so 12 is not a solution.

This leaves option C as the correct answer, because all of the solutions in the set (13, 14, and 15) are greater than 12.

Therefore, your answer is C.

Hope this helps!
