There are 30 balls numbered 1-30 in a bag. One is randomly selected 12 times. What is the probability of getting a prime number
Sliva [168]

Answer: The probability of getting a prime number exactly five times = 0.1908

Step-by-step explanation:

Prime numbers from 1 to 30 are 2,3,5,7,11, 13, 17, 19, 23, 29.

The probability of getting a prime number p= \dfrac{10}{30}=\dfrac13

Number of trials n = 12

Binomial probability formula:

P(X=x) = \ ^nC_x p^x(1-p)^{n-x}

, where x= number of successes

n= number of trials.

x = Number of successes

p= probability of getting one success.

The probability of getting a prime number exactly five times:

P(X=5)=\ ^{12}C_5(\frac13)^5(1-\frac13)^{7}

=\frac{12!}{5!7!}(\frac1{243})(\frac{128}{2187})\\\\=0.1908

Hence, the probability of getting a prime number exactly five times = 0.1908

The data below shows the minimum wage requirement
andreyandreev [35.5K]

Answer:

We select the option c.

y=0.114x+0.691

Step-by-step explanation:

<u>Best Fit Regression Model</u>

Scientists often wonder if there is a relationship between the variables under study. It's a vital matter in modern times where artificial intelligence technology is struggling to find answers where traditional approaches hadn't before.

The most-used tool to find relations between variables is the regression model and its best fit lines to try to find an expression who relates variable x (years from 1960) and variable y (minimum wage requirement) as of our case.

The data was entered into a digital spreadsheet and an automatic function was applied to find the best-fit model.

The automated tool's output was this equation:

y=0.11363x+0.6906

That can be rounded to three decimals

y=0.114x+0.691

We select the option c.
