Answer: 3 of your teeth have fillings

Step-by-step explanation: since is 30 teeth you have meaning is 100% but 10% is wilth fillings meaning

10% of the filling divided by the 100% which is the percentage of the teeth you have multiplied by the number of teeth you have which is 30

10/100*30=3

Meaning you have 3 filled teeth

MArishka [77]

Answer:

Option 3 is correct that is prime numbers.

Step-by-step explanation:

Even numbers are those which are divisible by 2

Prime numbers are the numbers which are divisible by 1 and the number itself

Since, we have to take only positive numbers

Carrie has taken out the set of even number within the set of prime number

So, 2 is the only number inside this eset because 2 is even as well as prime

Hence,universal set will be prime numbers

Therefore, Option 3 is correct that is prime numbers.

Answer:

$\frac{1}{6} ,\frac{1}{6} ,\frac{1}{36}\,,\,independent$

Step-by-step explanation:

Given: Let A be the event that the first die lands on 2 and B be the event that the second die lands on 2.

To find:

P(A), the probability that the first die lands on 2

P(B), the probability that the second die lands on 2

P(A and B): the probability that the first die lands on 2 and the second die lands on 2

Solution:

Probability refers to chances of occurrence of some event.

Probability = number of favourable outcomes/total number of outcomes

Sample space = $\left \{ 1,2,3,4,5,6 \right \}$

Total number of outcomes = 6

For P(A):

Number of favourable outcomes = 1

So,

$P(A)=\frac{1}{6}$

For P(B):

Number of favourable outcomes = 1

So,

$P(B)=\frac{1}{6}$

P(A and B) = $P(A)P(B)=\left ( \frac{1}{6} \right )\left ( \frac{1}{6} \right )=\frac{1}{36}$

Yes, A and B are independent events as happening of each of the event does not depend on the other.
