Question 7 • Probability and Statistics with Applications Honors Sem-2-FL-1210300 (2024-2025)

A popular board game has players twist their bodies around so that their hands and feet touch small colored dots. A spinner with equal areas for each body part (left hand, right hand, left foot, or right foot) is used. Which of the following is the correct probability distribution for the body part chosen to be placed?

Answer
A
LH RH LF RF 0.50 0.25 0.50 –0.25
B
LH RH LF RF 1 1 1 1
C
LH RH LF RF 4 4 4 4
D
LH RH LF RF 0.25 0.25 0.25 0.25

Explanation

The spinner has four equally sized sections, one for each body part, so each part is equally likely to be chosen. Each probability is 1 ÷ 4 = 0.25, and the four probabilities add up to 1. Choice D gives 0.25 for LH, RH, LF, and RF.
