Answer:
175/1001
Step-by-step explanation:
(a.)
Freshman: 5 Combination 2
sophomores: 7 Combination 3
Junior: 4 Combination 1
The combination of three groups :
=5c2 × 7c3 × 4c1
=10 × 35 × 4
=1400 ways
(b.)
=5+7+4=16
=2+3+1
Which is (16 combination 6)
The probability will be:
=(5c2 × 7c3 × 4c1) / 16c6
=1400/8008
=175/1001

Answer:
angle C = 36°
Step-by-step explanation:
Fun fact that I found out:
all interior angles of a triangle added together = 180°
5x + 3x + 2x = 180°
combine like terms:
10x = 180°
divide both sides of the equation by 10:
x = 18°
angle C = 2(18°) = 36°
