Based on a poll, 40% 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
(Round to three decimal places as needed.)

The probability under the given conditions is found:

P(7) = 0.079

Step-by-step explanation:

Let x be the number of adults who believe in reincarnation.

Adults randomly selected = 8

percentage of adult believe in reincarnation = 40% = 0.4

x follows binomial distribution:

P(x) =  

where

n= total people random people selected = 8,

x = selected for the part = 7,

p = probability given = 0.4

P(7) =

P(7)= (8)(0.0164)(0.6)

P(7) = 0.07872

Rounding off to 3 decimal positions

P(7) = 0.079

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6
