<u>Problem</u>
A bag contains 6 blue marbles, 10 red marbles, and 9 green marbles. If two marbles are drawn at random without replacement, what is the probability that two red marbles are drawn?
<u>Work </u>
Probability = no. of favorable outcomes /total no. of outcomes
Probability of getting a blue marble=5/5+6+9=5/20
Probability of getting a red marble=6/20−1=6/19
5/20×6/19
<u>Answer</u>
3/20
So it is C.
Answer:
No solution
Step-by-step explanation:
3(5x+7) = 30 + 15x
DISTRIBUTE
15x+21 = 30+15x
15x-15x = 0
So no solution
Answer:
y equals 3/2 - 1/2 x.......
