Replacement = 11 total
probability of choosing a consonant = 7/11
without replacing the card
probability of choosing an e = 3/10
probability of choosing both = 7/11 * 3/10 = 21/110 <===
Answer:
The variance of the given data is 106.9667
Step-by-step explanation:
The variance, S² of a sample is given by the expression;

Where:
= One of the observations
= The mean of the observations
n = Number in the sample = 6
The mean = Σ
/n = (26 + 32 + 29 + 16 + 45 + 19
)/6 = 167/6 = 27.833
Therefore, we have;
S² = ((26 - 27.833)²+(32 - 27.833)²+(29 - 27.833)²+(16 - 27.833)²+(45 - 27.833)²+(19 - 27.833)²)/(6 - 1) = 106.9667.
