Every day a kindergarten class chooses randomly one of the 50 state flags to hang on the wall, without regard to previous choice

Romashka [77]

Answer:

a) $S=50$

$P(X)=0.02$

b) $P(W,M,C)=8*10^-^6$

c) $P(W_2_3)=1.18*10^-^3$

Step-by-step explanation:

From the question we are told that

Sample space S=50

Sample size n=30

a)Generally the sample space S is

$S=50$

The probability measure is given as

$P(X)=\frac{1}{50}$

$P(X)=0.02$

Generally the probability that the class hangs Wisconsin’s flag on Monday, Michigan’s flag on Tuesday, and California’s flag on Wednesday is mathematically given as

Probability of each one being hanged is

$P(X)=\frac{1}{50}$

Therefore

$P(W,M,C)=\frac{1}{50} *\frac{1}{50}* \frac{1}{50}$

$P(W,M,C)=\frac{1}{125000}$

$P(W,M,C)=8*10^-^6$

c)Generally the probability that Wisconsin’s flag will be hung at least two of the three days is mathematically given as

Probability of two days hung +Probability of three days hung

Therefore

$P(W_2_3)=^3C_2 (1/50) * (1/50) * (49/50) +^3C_3 (1/50) * (1/50) *(1/50)$

$P(W_2_3)=148 / 125000$

$P(W_2_3)=1.18*10^-^3$

URGENT!!

I think the correct answer would be B. The graph in the attached image would most likely be described as a bimodal symmetric. A bimodal graph would be a graph which has two peaks. From the image, we have 3 peaks so it should be a multimodal but it is not in the choices the closest would be a bimodal one. Each group of the peak shows a symmetrical distribution since the left side and the right side are almost mirrors of each other which is seen for all the three peaks. So, the graph should be a bimodal symmetric distribution.
