9∉T means that 9 is not an element of the set T .
The probability that the spinner will land on c at least once is 5/9
<h3>How to determine the probability?</h3>
From the complete question, the probability that the spinner will not land on c when spun twice is:
P = 4/9
Using the complement rule, the probability that the spinner will land on c at least once is:
P' = 1 - P
This gives
P' = 1 - 4/9
Evaluate
P' = 5/9
Hence, the probability that the spinner will land on c at least once is 5/9

<u>We are given the proportion:</u>
6:n = 8:12
<u>rewriting as fractions:</u>
6 / n = 8 / 12
<u>Solving for n:</u>
6 = (8/12) * n [multiplying both sides by n]
n = 6 / (8/12) [dividing both sides by (8/12)]
n = 6*12 / 8
n = 9
