The probability of first rolling a 1, then a 5, will be .
<h3>
What is probability?</h3>
- Probability is an area of mathematics that deals with numerical descriptions of how probable an event is to occur or how likely a statement is to be true.
- The probability of an event is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.
- The greater the likelihood of an occurrence, the more probable it will occur.
To find the probability of getting a 1 the first time and a 5 the second time:
Probability of getting 1 in 1st time =
Probability of getting 5 in 2nd time =
The probability of first rolling a 1, then a 5, will be = ×
Therefore, the probability of first rolling a 1, then a 5, will be .

Step-by-step explanation:
I hope this helps.... :)
All of the following are acute angles.
Let and be the amounts of available alloy (AA) and pure magic steel that are used, so we also have
DA13 is supposed to contain 7% gold, 3% silver, and 90% steel, so that 2.7 kg of it is made up of
For each kg of the available alloy (AA), there is a contribution of 0.21 kg of gold, 0.09 kg of silver, and therefore 0.70 kg of steel; kg of it will contain kg of gold, kg of silver, and kg of steel. Each kg of magic steel of course contributes 1 kg of steel; kg of it will contribute kg of steel.
Then the dwarves need
• total gold:
• total silver:
• total steel:
Solve for and . The first two equations are consistent and give , and substituting this into the third we find . So the dwarves must combine 0.90 kg of AA and 1.80 kg of magic steel.
