Let Y be a random variable with a mean of 11 and variance 9. Using Chebyshev’s theorem to find the value of C such that P(|Y −11| ≥ C) ≤ 0.09.

For every 9 pieces in Ren's handful of trail mix, there are 2 raisins.

Step-by-step explanation:

Since we have given that

Number of peanuts = 6

Number of raisins = 4

Number of cranberries = 3

Number of chocolates chips = 5

Total = 6+4+3+5=18

If for every 9 pieces in Ren's handful of trail mix, there are 2 say'x'.

According to question,

And we know that there are 4 raisins.

Hence, for every 9 pieces in Ren's handful of trail mix, there are 2 raisins.
