<u>Given</u>:
Given that there are 10 marbles in a bag. 4 are blue, 3 are black, 2 are white and 1 is red.
The marbles are selected by not replacing the drawn ones.
We need to the probability of selected a black marble and then a white marble without replacement.
<u>Probability</u>:
Let B denote the black marble.
Let W denote the white marble.
The probability of selecting a black marble is 
The probability of selecting a white marble without replacement is 
The probability of selecting a black marble and then a white marble without replacement is given by
Substituting the values, we get;
Thus, the probability of selecting a black marble and then a white marble without replacement is 
Answer:
Option C
Step-by-step explanation:
The central Limit Theorem says the sampling distribution of the sample mean is approximately normal under certain conditions
The conditions are
i) the population should be symmetrial. If population is skewed sample size should be sufficiently large atleast 30
ii) Samples should be drawn strictly at random
iii) the sample observations should be independent
Thus we find that option a is not necessary because even for skewed large sample size allows the theorem
Option b is not correct since if population is less than 30, sampling itself is not necessary.
Option d is also wrong since normality is not necessary
Only option C) The sample size must be large (e.g., at least 30) is the necessary condition
69% can be written as
69/100
That cannot be reduced any further since 69 and 100 do not have any common factors other than 1
Answer:
C
Step-by-step explanation:
This one sounds the most confident, being a call to action. It is good to end a thought with motion.
3/4 cups of orange juice for 1 smoothie would be 3/4 x 2 = 2 smoothies.
3/4 (.75) x 2= 1 1/2 cups of orange juice.
