Answer: 0.001
Step-by-step explanation:
Given
The lock has 3 dials, each with the number 0 through 9.
The first place can be filled in 10 ways and the probability of selecting number '4' out of the 10 is
Similarly for selecting '3' and '9' is also ![\frac{1}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B10%7D)
Therefore the probability of getting a combination of 4-3-9 is
![\Rightarrow P=\dfrac{1}{10}\times \dfrac{1}{10}\times\dfrac{1}{10}\\\\\Rightarrow P=\dfrac{1}{1000}\\\\\Rightarrow P=0.001](https://tex.z-dn.net/?f=%5CRightarrow%20P%3D%5Cdfrac%7B1%7D%7B10%7D%5Ctimes%20%5Cdfrac%7B1%7D%7B10%7D%5Ctimes%5Cdfrac%7B1%7D%7B10%7D%5C%5C%5C%5C%5CRightarrow%20P%3D%5Cdfrac%7B1%7D%7B1000%7D%5C%5C%5C%5C%5CRightarrow%20P%3D0.001)
Answer:
A = 13
Step-by-step explanation:
To find the area of a triangle, multiply the base by the height, and then divide by 2.
13 x 2 = 26
26 / 2 = 13
Answer:
$25
Step-by-step explanation:
the fruit vendor sold 75-10 = 65 kg of bananas. 65*28 = 1820 dollars. so the fruit vendor earned 1820 dollars.
since she lost 55 dollars, 75 * cost = 1875, divide by 75 to get cost = 25
Answer:
g = (x - 2)/3
Step-by-step explanation:
x=3g+2 can be rearranged as:
3g + 2 = x
So, to make g the subject formula 3g must be placed alone
i.e 3g = x - 2
Now, to get the value of g, divide both sides by 3
3g/3 = (x - 2) /3
g = (x - 2)/3
Thus, the value of g is (x - 2)/3
