= You are bidding on six items available on an online shopping site. You think that for each bid you have a 25% chance of winning it, and the outcomes of the six bids are independent events. Let X denote the number of winning bids out of the six items you bid on. Find the probabilities. a. Explain why the distribution of X can be modeled by the binomial distribution. b. Find the probability that you win exactly 4 bids. c. Find the probability that you win 4 bids or fewer. d. Find the probability that you win more than 4 bids. R D. There is the same probability of success for each trial (bid). EXE The number of bids varies. VE The data are binary. XG. The trials are dependent. H. Probabilities of success for trials (bids) differ for each trial. b. The probability of winning exactly 4 bids is 0.0329 (Round to four decimal places as needed.) c. The probability of winning 4 bids or fewer is. (Round to four decimal places as needed.) SEP 20 Clear all 5 tv Check answer gr Å
