The following data are based on a survey taken by a consumer research firm.in this table x = number of televisions in household and % = percentages of u.s. households x 0 1 2 3 4 5 or more % 3% 11% 28% 39% 12% 7% what is the probability that a household selected at random has less than 3 televisions? select one: a. 0.81 b. 0.39 c. 0.42 d. 0.58

Probability is the study of determining the chances of an event being successful or not. To determine the probability of, say, 5 events happening, you would have to add their individual probabilities. For the probability of household having less than 3 televisions, you add the data for 2, 1 and 0 televisions.

Total Probability = 3% + 11% + 28% = 42% (or 0.42 if in decimal form)

I think A, but not 100%
