Answer:
6.2
Step-by-step explanation:
Although there's multiple ways to solve this problem, my method will be to simply find the area for the full triangle (the empty + orange triangles) and subtract the area of the smaller, empty triangle.
Now, you that area for a triangle is 1/2*base*height.
To find the measurements for the full triangle, you must add up the bases for the two smaller triangles:
Height is the same for both triangles so Height total = 4 ft.
Now the total area can be calculated:
Area total= 1/2* base_total * height_total
Area total = 1/2 * 5ft * 4 ft
Area total = 20 / 2 = 10 ft squared
Lastly, subtract the area of the empty triangle from the total triangle to find the orange triangle.
Area Empty Triangle = 1/2 * base_empty * height_empty
Area Empty Triangle = 1/2 * 1.9ft * 4 ft = 7.6 ft / 2 = 3.8 ft squared
Area total - Area empty = 10ft^2 - 3.8ft^2 = 6.2 ft squared
The answer is 067.
It takes an even number of steps for the object to reach (2,2), so the number of steps the object may have taken is either 4 or 6 .
If the object took 4 steps, then it must have gone two steps and two steps E, in some permutation. There are
ways for these four steps of occuring, and the probability is
.
If the object took 6 steps, then it must have gone two steps N and two steps E, and an additional pair of moves that would cancel out, either N / S or W/E. The sequences N, N, N, E, E, S can be permuted in ways. However, if the first four steps of the sequence are N, N, E, E in some permutation, it would have already reached the point (2,2) in four moves. There are
ways to order those four steps and
ways to determine the order of the remaining two steps, for a total of 12 sequences that we have to exclude. This gives
sequences of steps. There are the same number of sequences for the steps N, N, E, E, E, W, so the probability here is
.
The total probability is , and

What is probability?
- Probability is synonymous with possibility. It is a mathematical discipline that deals with the occurrence of a random event. The value ranges from zero to one.
- Probability has been introduced in mathematics to predict the likelihood of occurrences occurring. Probability is defined as the degree to which something is likely to occur.
- This is the fundamental probability theory, which is also utilized in probability distribution, in which you will learn about the possible results of a random experiment.
- To determine the likelihood of a particular event occurring, we must first determine the total number of alternative possibilities.
