Answer:
a) np > 5
d) nq > 5
Step-by-step explanation:
Binomial probability distributions depend on the number of trials n of a binomial experiment and the probability of success p on each trial.
A binomial distribution can be approximated with the help of normal distribution.
A binomial distribution has parameters:
where n is the number of independent trials and p is the probability of success.
If p is the probability of success, then we define probability of failure as:
A normal distribution can be used to approximate the binomial distribution if
Thus, the correct answer is
a) np > 5
d) nq > 5
Answer:
if the probability of a 6 is 1/5, the probability of “not six” is 4/5. The probability of a 6 on the first roll and not on the second is 1/5 x 4/5 = 4/25. The six could come on the second roll so that probability must be doubled. The overall probability of exactly one six is 8/25 or 0.32.

Answer:
Pie charts can generally be used instead of bar graphs
Step-by-step explanation:
A pie chart can be used instead of a bar chart. A pie chart is an alternative to the bar chart. Both of these can be regarded as data visualization tools. The pie chart shoes us generally how several parts makes up a whole. While the bar chart uses rectangular bars to show us the proportion of each of the categories of data
Answer: C, 7s + 3t and 3t + 7s.
Step-by-step explanation: Nothing is changing between the expressions except for their position. In addition, position does not matter though, so these two are the SAME EXPRESSION
