Using it's concept, the experimental probability that in a group of 4 students, at least one of them has green eyes is of 0.45 = 45%.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>. An experimental probability is calculated considering the results of previous trials.

In this problem, there were 20 trials. The digit 9, which represents a student with green eyes, appears at least once in 9 of the the trials, hence the probability is:

p = 9/20 = 0.45 = 45%.

madreJ [45]

Answer: a) $\dfrac{799}{31250}$ b) $\dfrac{30451}{31250}$

Step-by-step explanation:

Since we have given that

Number of days in a year = 365

Number of students = 50

Probability that no two students share the same birthday. It means each student has different birthday.

Probability(no two students share the same birthday) $=\dfrac{365-1}{365}\times \dfrac{365-2}{365}........\times \dfrac{365-50}{365}$

Probability(no two students share the same birthday) $=\dfrac{^{365}P_{50}}{365^{50}}$

Probability(no two students share the same birthday) $=\dfrac{799}{31250}\approx 0.025568$

Probability that at least one of the students has the same birthday as another student in the class is given by

$1-P(\text{no student share the same birthday})\\\\=1-\dfrac{799}{31250}\\\\=\dfrac{30451}{31250}=0.974432$

kvasek [131]

Answer:

After 50 years college will receive a amount of $294570.25

Step-by-step explanation:

We have given deposited amount P = $10000

Rate of interest r = 7 %

Time is given t = 50 years

We have to find the amount after 50 years which college receive

Amount is given by

$A=P(1+\frac{r}{100})^n$

$A=10000(1+\frac{7}{100})^{50}=294570.25$

So after 50 years college will receive a amount of $294570.25

Will Give Brainliest!<br><br><br>Find the function rule.

3241004551 [841]

<h3>Answer:</h3>

y = -5x -1

<h3>Step-by-step explanation:</h3>

Changes in x-values are constant and are +1.

Changes in y-values are constant and are -5.

Because the ratio of changes in y to changes in x is constant (-5/1) = -5, you know the function is linear. To write the equation, you can use the slope-intercept form, since you know the slope (-5) and the table shows the y-intercept: (x, y) = (0, -1).

The rule is ...

... y = -5x -1

What is the mean of this data set? {14, 7, 2, 8, 3} Enter your answer as a decimal in the box.

Assoli18 [71]

The mean of the data set is 6.8.

Mean is the average value of the given set of observations. In statistics, we also come across different types of mean such as Arithmetic, Geometric and Harmonic mean.

Given

The data set is 14, 7, 2, 8, 3.

The mean of the data set is given by;

$\rm Mean = \dfrac{Sum \ of \ all \ data}{Number \ of \ data}\\\\Mean =\dfrac{14+7+2+8+3}{5}\\\\Mean = \dfrac{34}{5}\\\\Mean=6.8$

Hence, the mean of the data set is 6.8.
