What is the probability of rolling a 6-sided die and getting a 1 or a prime number?

Answers

Answer 1

Answer:

The probability of rolling a 6-sided die and getting a 1 or a prime number is 0.66 or 66%.

What is the probability?

The probability is defined as the ratio of number of favourable outcomes and the the total number of possible outcome.

Assuming the die is numbered 1 to 6.

To answer the question, we first need to know many prime numbers can be represented on the die. What are the prime numbers equal to 6 or lower?

We have 2, 3 and 5. (since 4 and 6 are not prime numbers). So we have 3 prime numbers, plus the number 1... so there are 4 possibilities valid for rolling a 1 or a prime number: 1,2,3 and 5.

There 4 possibilities out of 6 total possible outcomes, the probability of rolling a 6-sided die and getting a 1 or a prime number is;

$\rm Probability=(4)/(6)\n\n Probability=(2)/(3)\n\n Probability=0.66$

Hence, the probability of rolling a 6-sided die and getting a 1 or a prime number is 0.66 or 66%.

Find the GCF of the following literal terms. m^7 n^4 p^3 and mn^12 p^5

Answers

Do you have the 4th problem typed correctly? The two given numbers have no factor (other than 1) in common (i.e., they are relatively prime) so the GCF is 1.

48 = 2^4 * 3

Therefore, GCF of 16a^4 b^4 + 32a^3 b^5 - 48a^2 b^6 is 16a^2 b^4, so
16a^4 b^4 + 32a^3 b^5 - 48a^2 b^6 = (16a^2 b^4)(a^2 + 2ab - 3b^2) = (16a

A lamp is on sale, and its price is reduced from $80 to $50. What is the percent of decrease? Select from the drop-down menu to correctly complete the statement.

Answers

The percentage decrease is equal to the change in price ( the decreased amount) divided by the original amount, then multiplied by 100. We have,

Percentage decrease = $(80-50)/(80)=0.375*100=37.5$ %

ANSWER: 37.5%

$80 - $50 = $30

$30 * 100 / $ 80 = 37.5%

answer: 37.5% of decrease.

A box of oranges weighs 4 kg. If one orange weighs 80 g, how many oranges are in the box?

Answers

Answer:

50 oranges

Step-by-step explanation:

Convert the measurements for them to be the same ie 4kg to g

1kg=1000g. 4kgx1000=4000g

4000g is the mass of all oranges

1 orange=80g

? =4000g that is 4000/80

=50 oranges

Answer:

50 oranges

Step-by-step explanation:

Since each orange is measured in grams, we convert the 4 kg to g to start.

4 kg is equal to 4000 g.

Each orange weighs 80 g, so we divide 80g into 4000g.

80 divided by 4000 equals 50.

50 oranges are in the box.

Which statement best explains why Step 2 is incorrect in Mona's solution?

She did not add 5 to 30.

She did not divide 30 by 5.

She did not multiply 30 by 5.

She did not multiply 30 five times.
