A die is rolled once. Find the probability of obtaining an odd number? 3. A bowl contains 20 chips numbered 1 to 20. If a chip is drawn randomly from the bmvl, what is the probabity that it is a. 12 or 20? b. 10 or an even number? 4. A bag contains 5 black marbles, 10 blue marbles, 4 yellow marbles, and 8 green marbles. A marble is randomly selected, replaced, and a second marble is randomly selected. Find the probability of selecting a black marble, then a blue marble. Let Us Apply Activity 3. There's more! 1. H'redimt: Give 3 examples of problems or situations in reallife that involve probability. in each example, a. explain the problem or situation. b. solve the problem 4?" HIIII 1-57 a 6 Activig) I. Got it! Direction: Consider the situation below, fillin the blanks the correct answer. Example. A die is rolled once. Find the probability of obtaining a 6? \"This problem is an example of a SIMPLE event. So, we use P(E]=number of ways the event can occurnumber of possible outcomes. Therefore the P (obtaining a six] = 16. 1. A die is rolled once. Find the probability of obtaining a prime number? ' This problem is an example of a event So, we use P(E]=number of ways the event can occurnumber of possible outcomes. Therefore the P (prime number] = _? 2. A bowl contains 20 chips numbered 1 to 20. If a chip is drawn randomly from the bowl, whatis the probability that it is a. 5 or 8? ' This problem is an example of a event So, we use PA or B=PA+P(B). Therefore the P (5 or 8) = _'? b. 6 or an even number? ' This problem is an example of a event So, we use PA or B=PA+PB-P(A and B). Therefore the P (6 or even) = _? 3. A bag contains 5 black marbles, 10 blue marbles, 4 yellow marbles, and 8 green marbles. Amarble is randomly selected, replaced, and a second marble is randomly selected. Find the probability of selecting a yellow marble, then a green marble. ' This problem is an example of a event So, we use 4 GSC-CID-LRMSESSLM w. oaoo E'ec aw.- jam: 14 2021 PA and B: PAx PB following A. . Therefore the P (yellow and green) = _'? III E) o
