Question

You pick two marbles from a bag containing 30 marbles: 3 green, 6 white, 4 red, 7 yellow, and 10 blue. Find the given probabilities. Show your work. Simplify all answers.

P(red)



P(blue)



P(white)


P(yellow)


P(green)

Answer 1

Total balls in bag(sample space)=30
Red balls=4
Green=3
White=6
Yellow=7
Blue=10
event P(E) = (Number of favorable outcomes) ÷ (Sample space).
So p(red)=no red balls/total balls in the marble
P(red)=4/30=2/15
P(blue)=10/30=1/3
P(white)=6/30=1/5
P(yellow)=7/30
P(green)=3/30=1/10
