amistre64 · Answer

you cant have an experimental prob without doing an experiment

amistre64 · Answer

20 answer choices and only 5 are right would amount to threoretical prob

this is my question my school gave me and I need a good answer

amistre64 · Answer

then my first reply would be a sufficient answer

find a test with 5 questions that have 4 multiple choices each, and that you dont know which answers are correct

then take the test

find out how many answers you got right ....

if i know how to do it, sure

amistre64 · Answer

$$\frac{\binom{5}{3}\binom{15}{2}}{\binom{20}{5}}$$

my gut on the first one is this, a hypergeometric probability; but im sure its wrong
