<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.
V = PI x r^2 x h/3
3.14 x 7^2 x 24/3
49 x 8 = 392
answer is 392PI units^3
answer is B
M to the power 4 squared minus 23

Answer:
Average speed = <em>7</em><em> </em><em>metre</em><em> </em><em>per</em><em> </em><em>second</em>
Step-by-step explanation:
Average speed ( v ) = distance / time
=》v = 350 / 50
=》v = 7
so, average speed = 7 m / sec
