There is only two multiples of three on a six-sided die, the 3 side, and the 6 side.

3 x 20 = 60
6 x 20 = 120
120 + 60 = 180

$180.00 is your possible winnings total, but the question asks for your expected value on EACH roll, so you divide 180 by 6(sides on a die) to get your final answer

180/6 = 30

ANSWER: D. $30.00

Henry had 15 quarters. He gave his sister 4 quarters. How much money does he have now??
telo118 [61]

Answer:

$2.75

Step-by-step explanation:

A quarter's value as placed on it by the U.S. Treasury Department is $0.25, or 1/4 of a dollar.

Henry had 15 quarters, in which he gives his sister 4: 15 - 4 = 11

Henry now has 11 quarters. Multiply 11 with 0.25: 11 x 0.25 = 2.75

Henry has $2.75

What method of assigning probabilities to a simple event uses relative frequencies?
Alex Ar [27]

The empirical method is the right answer.

Empirical probability is calculated by dividing the number of times an event was seen in your data by the entire sample size. An event's relative frequency is strongly connected to an empirical probability, also known as an experimental probability.

Empirical probability bases its estimation of the likelihood that a specific result will recur on the number of instances of that outcome within a sample set. In short, the empirical method uses relative frequencies to determine probabilities.

Here's another question with an answer similar to this about empirical method:
