Question

the median of 5, 7, 2, 9, 8 is: 1 point 5 7 8 6 a bag has 3 red, 5 blue, and 2 green 2 points marbles. whats the probability of picking a green marble? your answer

Explanation:

Step1: Sort the data

Sort the numbers \(2,5,7,8,9\).

Step2: Find the median

For \(n = 5\) (odd number of data points), the median is the \(\frac{n + 1}{2}\) -th value. \(\frac{5+ 1}{2}=3\) -rd value. The 3 -rd value in \(2,5,7,8,9\) is \(7\).

Step3: Calculate total marbles

Total marbles \(=3 + 5+2=10\)

Step4: Calculate probability of green marble

Probability \(P=\frac{\text{Number of green marbles}}{\text{Total number of marbles}}=\frac{2}{10}=\frac{1}{5}\)

Answer:

For the median question: \(7\)
For the probability question: \(\frac{1}{5}\)
