Answer: A 1/5
Explanation:
Probability of getting blue marble, red marble, white marble, and purple marble are 1/4, 2/5, 1/5 and 3/20 respectively.
What is probability ?
Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.
Given that,
Number of blue marbles = 5,
Number of red marbles = 8,
Number of white marbles = 4,
And number of purple marbles = 3.
Total number of marbles = 5 + 8 + 4 + 3 = 20
Probability of getting blue marble = number of blue marbles/total number of marbles
=5/20=1/4
Apply same formula,
Probability of getting red marble= 8/20 = 2/5
Probability of getting white marble = 4/20 = 1/5
Probability of getting purple marble = 3/20
