The correct answer would be C. Hope that helps.
Let X be a discrete binomial random variable.
Let p = 0.267 be the probability that a person does not cover his mouth when sneezing.
Let n = 18 be the number of independent tests.
Let x be the number of successes.
So, the probability that the 18 individuals, 8 do not cover their mouth after sneezing will be:
a) P (X = 8) = 18! / (8! * 10!) * ((0.267) ^ 8) * ((1-0.267) ^ (18-8)).
P (X = 8) = 0.0506.
b) The probability that between 18 individuals observed at random less than 6 does not cover their mouth is:
P (X = 5) + P (X = 4) + P (X = 3) + P (X = 2) + P (X = 1) + P (X = 0) = 0.6571.
c) If it was surprising, according to the previous calculation, the probability that less than 6 people out of 18 do not cover their mouths is 66%. Which means it's less likely that more than half of people will not cover their mouths when they sneeze.
Option C is correct.
try multiplying it out yourself. It should work
They all have to have common denominators
The common denominator is 32
3/4= multiply by 8/8= 23/32
3/16= multiply by 2/2= 6/32
11/32. Is. 11/32
1/8 multiply by 4/4 =. 4/32
Smallest to greatest is 1/8. 3/16. 11/32. 3/4
