A. Free Throw Shot - A player is awarded free throws whenever the player is fouled in a shooting motion. A free throw is counted as one point if the ball went in the basket and zero if it misses. Based on Piel's stats in his previous games, he makes 60% of his free throws. To improve, he shots 5 free throws every day in practice. Suppose the random variable, X, is the number of times Piel makes a basket in 5 free throw attempts. This illustrates a random experiment following a distribution with number of trials, n, equal to and probability of making a basket, p, equal to Accordingly, below is the probability distribution table for the number of baskets made in his practice, X. X P[X = x] 0 1 2 0.0102 0.0768 0.2304 3 0.3456 In his practice, the probability that he can get 2 to 4 points is the chance that he will make a perfect score is 4 0.2592 5 While

ACTIVITY NO. 5: COMPUTING PROBABILITY CORRESPONDING TO A GIVEN RANDOM VARIABLE NAME: . TRACK/STRAND & SEC.: SCORE: (HOW MANY SIBLINGS DO THE LEARNERS HAVE) In your Statistics class, the teacher wants to know the number of siblings the learners have. Teacher: How many of the class have 0 sibling? Class: (There were 2 learners who raised their hands.) Teacher: How many of you has 1 sibling? Class: (There were 10 learners who raised their hands.) This continues until 7 siblings. Suppose that we have the following table of frequencies. Let us use W to represent the number of sibling/s. Probability of the jRandom Variable (W) P(W) 2/50 = 0.04 = 4% 10/50= 0.2% = 20% 28/50=0.56%=56% 5/50=0.1 = 10% 3/50=0.06 6% 1/50=0.02 = 2% W= Number of siblings Frequency %3D 1 10 %3D 28 3 4 3 %3D 1 7 1 1/50-0.02 2% Total
