Two balls are selected one by one with replacement. What is the probability that the first is yellowand the second is red?B. What is the probability that the first is yellow and the second is red if the two balls aredrawn without replacement? A.Given that, there are 8 yellow balls and 4 red balls. Total 8+4=12 balls.Now, the event A is first ball is yellow and the second is red if two balls are selected one by onewith replacement.Thus, the probability of the event A is,8x4P(A) =12x12P(A) = }В.Now, the event B is first ball is yellow and the second is red if two balls are selected one by onewithout replacement.Thus, the probability of the event B is,8x4P(B) =12x11P(B) =Thus, the probability of the event B is .

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

Question

i have provided all data with answers so i need all explantion statical and ptopaplaity explanation please what evey explantion you have please write them

and thank you so much

There are 8 yellow and 4 red balls inside an urn.
A. Two balls are selected one by one with replacement. What is the probability that the first is yellow
and the second is red?
B. What is the probability that the first is yellow and the second is red if the two balls are
drawn without replacement?

A.
Given that, there are 8 yellow balls and 4 red balls. Total 8+4=12 balls.
Now, the event A is first ball is yellow and the second is red if two balls are selected one by one
with replacement.
Thus, the probability of the event A is,
8x4
P(A) =
12x12
P(A) = }
В.
Now, the event B is first ball is yellow and the second is red if two balls are selected one by one
without replacement.
Thus, the probability of the event B is,
8x4
P(B) =
12x11
P(B) =
Thus, the probability of the event B is .

Help me please
Please help me do this case study with explanations with the answers and the calculations on excel CASE STUDY: Ya Ya's Yogurt. Last year Ya Ya Yogurt's decided to enter the flavored yogurt market, and it began cautiously by producing, distributing, and marketing a single flavor—a blueberry-flavored yogurt. The company’s initial venture into the yogurt market has been very successful; sales of blueberry are higher than expected, and consumers’ ratings of the product have a mean of 80 and a standard deviation of 25 on a 100-point scale for which 100 is the most favorable score and zero is the least favorable score. Past experience has also shown Ya Ya's that a consumer who rates one of its products with a score greater than 75 on this scale will consider purchasing the product, and a score of 75 or less indicates that the consumer will not consider purchasing the product. Emboldened by the success and popularity of its blueberry-flavored yogurt, Ya Ya's management is now considering the…
