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)

  1. P\frac{NT}{NL} = \frac{P\frac{NT}{NL} }{P\frac{NT}{NL} +P\frac{NT}{L} }
  2. \frac{0.7708}{0.7708+00108}
  3. \frac{0.7708}{0.7816}
  4. 0.98618219 (Simplify)

<u> Terms Of Percentages</u>

0.98618219 × 100

=98.6

Therefore your answer is 98.6% (Option D)

APEX

In a bag of candy, Marsha found that there were 7 red, 8 blue, 5 yellow, and 9 greens pieces of candy. Marsha put all of the pie
son4ous [18]

Answer:

Step-by-step explanation:

1) find the total candies

7 + 8 + 5 + 9 = 29

2) a probability can be expressed with a fraction whose denominator is the total candies, while the numerator represents the candies that we want to find

- red = 7/29

- blue = 8/29

- yellow = 5/29

- green = 9/29

3) compound probability

(red + blue)/29 = 15/29

(yellow + green)/29 = 14/29

(blue + yellow + green)/29 = 22/29
