1/16

Step-by-step explanation:

Spinner is divided into 8

The total possibilities when you spin once = 8

Numbers divisible by 3 = 3, 6

There are 2 numbers divisible by 3

Probability of getting number divisible by 3 = numbers divisible by 3/total possibility

Probability of getting number divisible by 3 = 2/8

Probability of getting number divisible by 3 two times in a row:

The two events are independent of one another. The probability of spinnig the first one will not affect the probability of spinning the 2nd one

Probability of getting number divisible by 3 two times in a row = Probability of getting number divisible by 3 × Probability of getting number divisible by 3

= 2/8 × 2/8 = 4/64

simplify = 1/16

Probability of getting number divisible by 3 two times in a row = 1/16
