Hallie is trying to win the grand prize on a game show. Should she try her luck by spinning a wheel with 6 equal sections labeled from 1 to 6 and hope she gets a 5, or should she roll two number cubes and hope she gets the same number on both cubes. Show your work?
A. likely
B. unlikely
C. There is a greater chance in picking to purple marbles because there are less of the white and more purple.
Hallie should spin the wheel because u have a greater chance of landing on a 5 then rolling two number cubes and hoping both number cubes come to equal 5.

Answer:
Step-by-step explanation:
Answer:
Area: 5π/2 in²
Perimeter: (3π+2) in
step-by-step explanation:
Area =
larger semicircle + small semicircle
= ½(pi × r1²) + ½(pi × r2²)
r1 = 2 in
r2 = 2/2 = 1 in
Area:
½(pi × 2²) + ½(pi × 1²)
= 2pi + ½pi
= 5pi/2 in²
Perimeter:
½(2pi × r1) + ½(2pi × r2) + r1
½(2pi × 2) + ½(2pi × 1) + 2
2pi + pi + 2
3pi + 2
