Total = 5+8 +4 +3 =20
P( red) = 8/20 = 2/5 = 0.4
P( red) = 8/20 = 2/5 = 0.4
Given:
Blue marbles = 5
Red marbles = 8
White marbles = 4
Purple marbles = 3
Total number of marbles = Blue + Red + White + Purple = 5 + 8 + 4 + 3 = 20
The chance of getting a red marble can be calculated as:
(Number of red marbles / Total number of marbles) * 100
Chance of getting a red marble = (8 / 20) * 100 = 40%
Therefore, there is a 40% chance of picking a red marble from the jar.
The total number of marbles in the jar is the sum of blue, red, white, and purple marbles: 5 + 8 + 4 + 3 = 20.
The number of red marbles is 8.
To calculate the probability, divide the number of red marbles by the total number of marbles:
Probability of getting a red marble = Number of red marbles / Total number of marbles
= 8 / 20
= 0.4 or 40%
So, the chance of picking a red marble is 40%.
