About Cindy M Expertise I can help with math through algebra and geometry -- not trig and not calculus. I can help with fractions, percents, decimals, using other bases, word problems, etc.
Experience I majored in math in high school and have scored very high on standardized tests.
Your video tape collection contains 5 history, 6 science fiction and 3 adventure movies.If you pick two tapes, what is the probability that they are both adventure movies?
thank s
Answer Hi David,
Probability is a fraction: # of 'winners' [outcomes that meet the conditions] over all possible outcomes.
For the 1st pick we have 3 winners / 14 outcomes
For the second pick, we have 2 remaining winners / 13 remaining outcomes
To find the complete probability multiply 3/14 * 2/13 = ?
Hope this is helpful. Write again whenever I can assist further.
