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)

A club has money for a trip. The expenses for the trip are shown below:
KonstantinChe [14]

Answer:

3/100

Step-by-step explanation:

convert these measurements into one unit, I am going to do decimals but you can sue fractions or percentages as well.

1/4 is 0.25

2/5 is 0.4

0.12 is 0.12

20% is 0.2

if you add all these up, it equals 0.97

1- 0.97= 0.03

you therefore have 0.03 of the money left over

this as a fraction is 3/100
