Based on a poll, 50% of adults believe in reincarnation. Assume that 8 adults are randomly selected, and find the indicated probability. Complete parts (a) through (d) below. a. What is the probability that exactly 7 of the selected adults believe in reincarnation? The probability that exactly 7 of the 8 adults believe in reincarnation is 0.004 (Round to three decimal places as needed.)

three randomly selected households are surveyed the numbers of people in the households are 2,6 and 7 assume that samples of size n=2 are randomly selected with replacement from the population of 2,6 and 7 listed below are the nine different samples
2,2 2,6 2,7 6,2 6,6 6,7 7,2 7,6 7,7
A) find the variance of each of the nine samples then summerize the sampling distribution of the variances in the format of a table representing the probability distribution of the distinct variance values
| S^2 | Probability |
| 0, 0.3, or 0.3 | |
| 1, 6.3 or 0.5 | |
| 8, 4 or 25 | |
| 40.5, 6.3 or 12.5 |
