The probability that exactly 4 of the selected adults believe in reincarnation is 5.184%, and the probability that all of the selected adults believe in reincarnation is 7.776%.

Given that based on a poll, 60% of adults believe in reincarnation, to determine, assuming that 5 adults are randomly selected, what is the probability that exactly 4 of the selected adults believe in reincarnation, and what is the probability that all of the selected adults believe in reincarnation, the following calculations must be performed:

0.6 x 0.6 x 0.6 x 0.6 x 0.4 = X
0.36 x 0.36 x 0.4 = X
0.1296 x 0.4 = X
0.05184 = X
0.05184 x 100 = 5.184

0.6 x 0.6 x 0.6 x 0.6 x 0.6 = X
0.36 x 0.36 x 0.6 = X
0.1296 x 0.6 = X
0.07776 = X
0.07776 x 100 = 7.776

Therefore, the probability that exactly 4 of the selected adults believe in reincarnation is 5.184%, and the probability that all of the selected adults believe in reincarnation is 7.776%.
