<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:
15
Step-by-step explanation:
To solve this, divide 192 by 8:
192/9 = 24
Subtract 9 from 24:
24 - 9 = 15
Therefore, 8 times the sum of 9 and 15 is 192
Step-by-step explanation:
Subtracting equation (2) from equation (1)
Substituting d = - 3 in equation (1), we find:
Hence, first term is zero.
Has someone answered this I need the answer...do u know it??
Step-by-step explanation:
- 3 1/2 can be rewritten as - 3 2/4
New equation will make it easier to combine like terms:
- 5 3/4 - 3 2/4
- 5 - 3 = - 8
3/4 + 2/4 = 5/4
You now have - 8 5/4. Simplify to get - 9 1/4.
Your answer is option C.
