A team of 4 people participates in a 400 -yard relay. And each team member runs the same distance and completed the race in a total of 53.2 seconds.

Answer:
2:1
2=5780
1=2890
Step-by-step explanation:
2/2+1=2/3×86,70=5780
1/2+1=1/3×8670=2890
There is to say, for each first roll, we start out with six possibilities; for each of these, there are six possibilities for the second roll; finally, for each second roll, there are six possibilities for the third. So, 6 cubed. So, 216 is our denominator, i.e., the number of all possible outcomes.
Answer: 216
