Answer:
(3C1 × 4C1)/12C2
Step-by-step explanation:
Total electives = 3 + 4 + 5 = 12
Art: 3C1
History: 4C1
1 Art & 1 History = 3C1 × 4C1
Probability = (3C1 × 4C1)/12C2

Answer:
Step-by-step explanation:
You must assume that N is the center of the circle.
NTP is a right triangle.
NM is the radius
NT is also a radius
The area of the circle is 25pi
25 pi = pi r^2
r^2 = 25
r = 5
The right angle triangle can be solved by
PT^2 + NT^2 = (r + 4)^2
PT^2 + 25 = (5+4)^2
PT^2 + 25 = 81
PT^2 = 56
PT = sqrt(56)
PT = 7.48
