Answer:
the probability of picking the red marble = 8.33%
Step-by-step explanation:
picking a red marble from 4 white marbles and 7 green marbles
total marbles = 1 red + 4 white + 7 green
total = 12 marbles
the ratio of picking 1 red marble over 12 marbles
is 1 / 12 = 0.083 x 100%
= 8.33 %
therefore,
the probability of picking 1 red marble = 8.33%
