Question

A spinner numbered 1 through 5 is spun 3 times. What is the probability of spinning a number less than 3 each time? Are these events dependent or independent?
(Points : 1)
Option A: 8/125; dependent

Option B: 1/15; independent

Option C:8/125 ; independent

Option D: 1/15; dependent

Answer 1

What are the odds of being below 3? Does the previous spin impact the next spin?

Answer 2

One spin does not impact the other, so it is independent. The odds of spionning below 3 is 60% or 0.6

Answer 3

To find the odds of doing it more than once, multiply it by itself. (you raise it to the power of the amount of trials)

Answer 4

odds of spinning number below 3 is 40%

Answer 5

or 2/5

Answer 6

So the odds are (.4)(.4)(.4) or .4^3= .064 To find the percent multiply by 100. It is a 6.4% to spin below 3 3 times.

Answer 7

for 3 throws it is 2/5 * 2/5 * 2/5

Answer 8

...

Answer 9
