x is the number of times the dial lands on region a or b.

The Dial on the Spinner is Spun 2 times in a row.

X= Number of times the dial lands on region A or B.

Variable X can take values =0 , 1, 2

There are three regions.

0=Neither on region A nor on region B

1= Region A

2= Region B

Considering equal probabilities of three regions

→Probability (Neither on region A nor on region B)=Probability (Region A)=Probability(Region B)

When, x=0

Means 2 failure and 0 Success that is 2 times neither on region A nor on region B

Probability (X=0 success)

Probability (X=1 success), one time on region A or B, and one time neither on region A nor on region B

Probability (X=1 success), one time on region A or B, and one time neither on region A nor on region B

Option A:

X                             P

0                  

1                      

2                          

step-by-step explanation:

1. the cylinder is a. 54

2.   a.108 /

the answer is 0.000652422

but if you ment to ask what is 6131 divided by 4, it is 1532.75.
