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

(WILL GIVE BRAINLIEST)

Answer:

m<I=57

m<J=57

m<K=66

Step-by-step explanation:

All the angles in a triangle add up to 180 degrees.

m<I= 3x+18

m<K= 5x+1

m<I is congruent to m<J.

We can plug the information we already know into the equation.

3x+18+3x+18+5x+1=180

11x+37=180

Subtract 37 from both sides.

11x=143

x=13

Now, we can find out what the angles are.

m<I= 3x+18

m<I=3(13)+18

m<I=39+18

m<I=57

We know that m<I=m<J, so they are both equal to 57 degrees.

m<J=57

Now for m<K:

m<K=5x+1

m<K=5(13)+1

m<K=65+1

m<K=66

We know this is correct because 57+57+66=180.
