Answer:
47.52% probability that among 10 randomly observed individuals fewer than 3 do not cover their mouth
Step-by-step explanation:
For each individual, there are only two possible outcomes. Either they cover their mouth when sneezing, or they do not. The probability of an individual covering their mouth when sneezing is independent of other individuals. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
According to a study done by Otago University, the probability a randomly selected individual will not cover his or her mouth when sneezing is 0.267.
This means that
What is the probability that among 10 randomly observed individuals fewer than 3 do not cover their mouth
10 individuals, so n = 10.
In which
47.52% probability that among 10 randomly observed individuals fewer than 3 do not cover their mouth
Answer:
a. Variable term
b. Variable term
Explanation:
a) We were given the algebraic expression:
The first term of the algebraic expression is:
The first term is a variable term
The variable is "y" and its coefficient is "-5"
b) We were given the algebraic expression:
The second term of the algebraic expression is:
The second term is a variable term
The variable is "b" and the coefficient is "-6"
I’m assuming you mean plus so it would be 7 cm if you mean multiplication then still 6 cm
