Answer:
Since we know that the probability that a randomly selected student has at least 1 household member who smokes is 0.421. Then the total who correspond to Cell 8 on this case is 0.421*1000 = 421
Step-by-step explanation:
We assume the following table:
No Hou. smokes >=1 hou. smokes Total
______________________________________________________
Student indicates he Cell 1 Cell 2 Cell 3
or she has asthma
_______________________________________________________
Student indicates he
or she does not have Cell 4 Cell5 Cell 6
asthma
_______________________________________________________
Total Cell 7 Cell8 1000
We are assuming a grand total of 1000 people for this case
Since we know that the probability that a randomly selected student has at least 1 household member who smokes is 0.421. Then the total who correspond to Cell 8 on this case is 0.421*1000 = 421
Answer:
And we can find the individual probabilities like this:
And adding we got:
Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
Solution to the problem
For this case we want to find this probability:
And we can find the individual probabilities like this:
And adding we got:
C=10 & P=5
3C+4P=50
C+P=15
Solve
3C+4P=50
3C+3P=45
Subtract
P=5
Substitute in equation 2
C+P=15
C+5=15
C=10
Answer:
Wait I only see the part where it says “what is the y-intercept and x-intercept of” but I don’t see an equation :/
