| What is the probability that a book that was purchased was for either English or Zoology? |
In Pre-Algebra today, students received their Chapter Nine Formative Pretests back from Mr. Giomini. Lesson 9.2 - Experimental Probability was introduced and modeled by Mr. Giomini. Students then worked with an assigned partner to complete the two problems listed below:
- A movie theater sells popcorn in small, medium, large and jumbo sizes. The customers of the first show purchase 4 small, 20 medium, 40 large and 16 jumbo containers of popcorn. Find the probability of the following scenarios:
- P(large container)
- P(small) or P(jumbo)
- There are 45 people in a restaurant. Of the 45, 20 are female and 25 are male. Calculate the experimental probability that the next person who walks in will be a male.
- find the probability of an event by using the definition of probability.
For Evening Practice, the student is expect to...
- answer questions one through fifteen on pages 453 and 454.
Good Job Mr. Giomini
ReplyDeletethe probability that a book was purchased for either English or Zoology is 2/4 or 1/2 which is 50%

The probability that a book was purchased was for either English or Zoology is 60 to 129 because if you add up the books that were bought for English and Zoology 46+24=60 so thats the number of books on English and Zoology and now you have to find the total of the the books so you add up every number 46+24+44+25=129 so the probability that a book was purchased for English and Zoology is 60 to 129.
ReplyDelete-Anthony 4th period
the probability is 20/43
