4. Hello class…. Tell me with emoji you’re feeling today… Which emoji are you today??

5. Let’s have a recall… Directions: Fill in the blank with the correct form of word.

6. ________________ is the chance that something will happen. ___________________________ is a chance process that leads to a well-defined result called an outcome. _______________ is the result of a single trial of an experiment. ___________________ is the set of all the possible outcomes. _________________ is just one of the possible outcomes. ___________ is any set of one or more outcomes satisfying some given conditions. Probability Probability Experiment Outcome Sample space Sample point Event

7. Picture Perfect I will present you with different pictures of objects, and you will give the fraction form of what is being asked.

8. the number of the syringes over all the objects the number of the virus picture over all the objects    

9. the shaded part the unshaded part      

10. the number of the word UP over all the words in the picture how about the word MAKE? how about the word ART?      

11. the number of the word MATH over all the words in the picture how about the word IS? how about the word FUN?      

12. the number of the word I over all the words in the picture how about the word LOVE? how about the word MATH?      

13. Probability of simple Events Probability is the chance that something will happen. How do we calculate or solve probability? P(event) = number of favorable outcome/s_ number of all possible outcomes P (event) = __ number of expected events____ number of all possible outcomes

14. Examples: What is the probability of getting a tail in tossing a single coin? P(tail) = 1 2 2. What is the probability of getting a HEART from a deck of cards?  P(heart) = 13 = 1 52 4 3. There are 20 marbles in a box. 4 are red, 5 are blue and 11 are yellow. What is the probability that a yellow marble will be picked? P(yellow marble) = 11 20

15. Let’s try this          

16. What’s in the box? A box contains 7 red balls , 5 orange balls , 4 yellow balls , 6 green balls , and 3 blue balls . What is the probability of drawing out: a. an orange ball? b. a red ball? c. a yellow ball? d. a green ball? e. a blue ball?

17. Numbers, numbers, numbers… Direction: Find the probability of the following simple events. Given: Set J = { 1, 2, 3, 4, 5, 6, 7, 8, 9}   1. even numbers 2. odd numbers 3. prime numbers 4. number divisible by 3 5. number divisible by 4

18. Group Activity         5. green candy Answer

19. generalization What is a probability? Probability is the chance that something will happen. How can we calculate or solve probability? P(event) = number of favorable outcome/s_ number of all possible outcomes P (event) = __ number of expected events____ number of all possible outcomes
