The probability of randomly selecting a yellow marble out of the bag is \frac{1}{5}

Step-by-step explanation:

A bag contains:

  • 7 red marbles
  • 5 yellow marbles
  • 6 blue marbles
  • 4 green marbles
  • 3 orange marbles

We need to find the probability of randomly selecting a yellow marble out of the bag

Probability is the ratio of number of favorable outcomes to the total number of possible outcomes P(A) = \frac{n(A)}{n(outcoms)}

∵ A bag contains 7 red marbles, 5 yellow marbles, 6 blue

   marbles, 4 green marbles, and 3 orange marbles

- Add all the color to find the number of total marbles

∴ n(all) = 7 + 5 + 6 + 4 + 3 = 25

∵ There are 5 yellow marbles

∵ P(yellow) = \frac{n(yellow)}{n(all)}

∴ P(yellow) = \frac{5}{25}

- Divide up and down by 5 to simplify the fraction

∴ P(yellow) = \frac{1}{5}

The probability of randomly selecting a yellow marble out of the bag is \frac{1}{5}

nexus9112 [7]

Answer:

Mean = 75

Median = 80

Mode = 85

The mode

Step-by-step explanation:

Given the data :

45 45 50 50 55 60 70 75 75 80 80 85 85 85 85 90 95 95 95 100

Rearranged data :

45, 45, 50, 50, 55, 60, 70, 75, 75, 80, 80, 85, 85, 85, 85, 90, 95, 95, 95, 100

The mean score :

ΣX / n ; n = sample size = 20

ΣX = 1500

Mean = 1500 / 20 = 75

Mode = most frequently occurring = 85 ( frequency of 4)

Median = 0.5(n + 1)th term

Median = 0.5(20 + 1)th term

Median = 0.5(21) th term

Median = 10.5th term = (10 + 11)th term / 2

Median = (80 + 80) / 2 = 160 / 2 = 80

2.) The mode
