Answer: The required probability that Maria will wear blue dress at her party is 16.67%.
Step-by-step explanation: Given that Maria has three red dresses, two white dresses and one blue dress.
We are to find the probability that Maria will wear a blue dress at her party.
Let S denotes the sample space of selecting a dress from the collection of Maria and A be the event that Maria wear blue dress at her party.
Then, we have
Therefore, the probability of event A is given by
Thus, the required probability that Maria will wear blue dress at her party is 16.67%.

<span>Given that the railroad rail is 6 kilometers before expansion.
When the railroad expands, it makes an isosceles triangle at the center of the rail.
The base of the triangle is 6 kilometers while each leg of the triangle is given by (6 + 10/100,000) / 2 = 6.0001 / 2 = 3.00005 kilometers.
[recall that 100,000 centimeters gives 1 kilometers, thus 10 centimetres gives 10/100,000 kilometers]
Taking one half of the isoceles triangle, we have a right triangle with one of the leg as 6 / 2 = 3 kilometers and the hypothenus = 3.00005 kilometers.
Thus, using the Pythagoras theorem, we find the other leg (height) of the right triangle as follows.
Let the other leg of the right triangle be h, then
Thus, the center of the rail will rise 0.01732058 kilometers above the ground.
But, there are 1,000 meters in 1 kilometers, therefore, </span><span><span>the center of the rail will rise 0.01732058 x 1,000 = 17.32 meters above the ground.</span></span>
