A spinner has five sectors of equal size. The sectors are labeled 1, 2, 3, 4, and 5. The spinner is spun twice. X is the number of times 3 is spun.

Drag each bar on the horizontal axis to the correct location to create a probability distribution for X.

A spinner has five sectors of equal size. The sectors are labeled 1, 2, 3, 4, and 5. The spinner is spun twice. X is the number of times 3 is spun.

Drag each bar on the horizontal axis to the correct location to create a probability distribution for X.

Draw a box like this one and put the 2 possible throws in it.

Down the side is the first throw, and along the top is the second throw,

I've added a couple so you can see what I mean

There are 25 boxes altogether, that is called the size of the sample space.

Now just count how many boxes fit each requirement,

for example, there is only one box where a three is spun both times so

the probability of getting 2 threes will be 1/25 = 0.04

Please let asker guest work it out from here.
