Answer: [tex]\bold{\dfrac{3}{38}=7.9\%}[/tex]
Step-by-step explanation:
There are 20 total marbles and 6 of them are red.
The first draw has a probability of 6 red out 20 total marbles.
The second draw has a probability of 5 remaining red out of 19 remaining marbles
1st draw and 2nd draw
[tex]\dfrac{6}{20}[/tex] × [tex]\dfrac{5}{19}[/tex] [tex]=\dfrac{30}{380}\qquad =\dfrac{3}{38}\qquad =7.9\%[/tex]
