Determine whether the distribution is a discrete probability distribution. x âp(x) 0 0.21 1 0.28 2 0.02 3 0.28 4 0.21 is the distribution a discrete probabilityâ distribution? why? choose the correct answer below. a. no comma because the total probability is not equal to 1. b. no comma because some of the probabilities have values greater than 1 or less than 0. c. yes comma because the distribution is symmetric. d. yes comma because the probabilities sum to 1 and are all between 0 and 1 comma inclusive.

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
