Aleksandr-060686 [28]

<h3>The probability of selecting a random student who is enrolled in both the courses is 0.280.</h3>

Step-by-step explanation:

Here, the total number of freshman in the university = 500

The number of students enrolled in Economics = n(E) = 323

The number of students enrolled in Mathematics = n(M) = 205

The number of students enrolled in Both Economics and math

= n(E∩M ) = 140

Let F : Event of selecting a student who is enrolled in both the courses

So, from the given data:

$P(F) = \frac{\textrm{Total number of favorable outcomes}}{\textrm{Total number of outcomes}} \\= \frac{\textrm{Total number of students enrolled in BOTH courses}}{\textrm{Total number of students}} \\ = \frac{140}{500} = \frac{7}{25}$

So, the probability of selecting a random students who is enrolled in both the courses is $(\frac{7}{25} ) = 0.280$

C) Yes, the triangles are congruent because the triangles have exactly the same size and shape

Step-by-step explanation:

B) From the image below an 180 degree angle would be obtuse in which neither angle appears to be so they are not supplementary.

C) They are congruent because they are taking angles of the same angles as one another just on different sides of the shape.
