The number of pages printed before replacing the ink in a printer is normally distributed with a mean of 10,500 pages and a standard deviation of 500 pages. A printer's ink has just been refilled. The probability that less than 11,200 pages will be printed is: a. 0.0808 b. 0.9192 c. 0.5674 d. 0.4192 A certain type of ochro seed germinates 75% of the time. A backyard farmer planted 6 seeds. The probability that exactly 3 seeds germinate is: a. 0.7910 b. 0.7869 c. 0.1318 d. 0.4567 If n=15 and p=0.75, then the mean of the binomial distribution is: a. 11.25 b. 8.00 c. 0.67 d. 8.90
