A contestant on the Cash Show just answer a trivia question correctly. This question had 5 multiple choice answers. It is estimated that 10% of the general population know the correct answer to this question. What is the probability that contestant knew the answer rather than guessed it

10% probability that contestant knew the answer rather than guessed it

Step-by-step explanation:

Since it is estimated that 10% of the general population know the correct answer to this question, for each contestant, there is a 10% probability that he knew the answer rather than guessing.

So the answer is 10% probability that contestant knew the answer rather than guessed it

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.
