Answer:
96
Step-by-step explanation:
The ratio of the measure of sides of a triangle are 8:15:17
The perimeter is 480
8x + 15x + 17x= 480
40x= 480
x = 480/40
x = 12
Therefore the measure of the shortest side of the triangle can be calculated as follows
8x
8×12
= 96
Answer: The required probability is 
Step-by-step explanation:
Since we have given that
Number of people came into Brad's store = 48
