6/(1/2)= 3 3>2
1/2 /6= 1/12 1/12<6
6x1/2=3 3>2
6x2=12 12>1/2
Answer:
The correct answer would be 4. Explanation below
Step-by-step explanation:
-6x-11x = 68
-6x-11x = -17x
-17x = 68
68/-17 = 4

Answer:
0.230
Step-by-step explanation:
Probability of an adult being in excellent health = p = 37% = 0.37
- There are only 2 outcomes of the event i.e. in excellent health or not.
- Number of trials is fixed i.e. n = 13
- Probability of success is constant
- Events are independent i.e. answer of individuals is not influenced by answers of others
This satisfies all the 4 conditions that are needed for a Binomial Experiment. Hence, we can solve the given question using Binomial Probability.
p = 0.37
q = 1 - p = 1 - 0.37 = 0.63
n = 13
We need to find the probability that when 13 adults are randomly selected, 3 or fewer are in excellent health i.e. P( x ≤ 3 )
P( x ≤ 3 ) = P(0) + P(1) + P(2) + P(3)
The formula of Binomial probability is:
So,
Thus,
P( x ≤ 3 ) = P(0) + P(1) + P(2) + P(3) = 0.0025 + 0.0188 + 0.0663 + 0.1427
P( x ≤ 3 ) = 0.2303
Therefore, the probability that when 13 adults are randomly selected, 3 or fewer are in excellent health is 0.230
