The problem asks for the probability that the product of two numbers, one drawn from each box, is an even number.
First, let's list the numbers in each box and identify whether they are odd or even.
| Box | Numbers | Odd Numbers | Even Numbers | Count (Odd) | Count (Even) | Total Count |
|---|---|---|---|---|---|---|
| 1 | $3, 6, 9, 12, 15$ | $3, 9, 15$ | $6, 12$ | 3 | 2 | 5 |
| 2 | $6, 11, 16, 21, 26$ | $11, 21$ | $6, 16, 26$ | 2 | 3 | 5 |
The total number of possible outcomes is the product of the number of chips in each box.
Total Outcomes = (Chips in Box 1) $\times$ (Chips in Box 2) = $5 \times 5 = 25$.
The product of two numbers is odd only if both numbers are odd. It's often easier to calculate the probability of the complementary event (product being odd) and subtract it from 1.
The probability of the product being even is 1 minus the probability of the product being odd.
$P(\text{Even Product}) = 1 - P(\text{Odd Product})$
$P(\text{Even Product}) = 1 - \frac{6}{25} = \frac{25}{25} - \frac{6}{25} = \frac{19}{25}$.
The probability for the product to be an even number is $\frac{19}{25}$.
If the data are skewed, which option of central tendency measure is the most unreliable indicator?
In a negatively skewed distribution
If the distribution is negatively skewed, then the:
The first four moments about the mean of distribution are 0, μ 2, 0.7 and 18.75. If the distribution is mesokurtic, the value of μ 2, is
If Mean > Median > Mode, the distribution is:
