Next week is the first TSML (Texas State Math League) contest. All Pre-AP and AP students are encouraged to take part in the contest. It is a 30 minute - 6 question test. Students are allowed to use a calculator. AP Statistics offers one point on a test for each problem answered correctly. Please plan to participate on Tuesday October 21, after school in room 332, 335, or 338.
To get you in the spirit of the contest, I have copied a previous problem from TSML(1 of the difficult ones) pertaining to probability below. A worked out solution with a correct answer could earn you up to five bonus points. If interested, please turn in your solution by Tuesday, 10/21/2009. Enjoy!
All students at the Academy of Music and Math take both music and math. The probability that a student has an A in math is 1/6. The probability that a student has an A in music is 5/12. The probability that a student with an A in music has an A in math is 7/10. What is the probability that a student has A's in both subjects?
