Given the data below, determine the probability that a person randomly selected from Group 1 will be wearing jeans.

A
0.37
B
0.48
C
0.52
D
0.63

1
First, identify the total number of people in Group 1. This is the sum of people wearing jeans and not wearing jeans in Group 1.
From the table, the number of people wearing jeans in Group 1 is 68, and the number of people not wearing jeans is 63.
Calculate the total number of people in Group 1 by adding the two numbers: 68 (wearing jeans) + 63 (not wearing jeans).
To find the probability that a person randomly selected from Group 1 is wearing jeans, divide the number of people wearing jeans by the total number of people in Group 1.
The probability is given by the formula: Probability = (Number of people wearing jeans in Group 1) / (Total number of people in Group 1).
