In a doctor's waiting room 12 people are waiting to be seen; 7 claiming to have just a cold, 3 claiming to have a fever and a cold, and 2 claiming to have just a fever. What is the probability a person waiting to be seen claims to have a cold or a fever

P( person waiting to be seen claims to have a cold or fever ) = 7 + 2 = 9

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
