Answer:
30/169
Step-by-step explanation:
We need to know how many marbles in the bag
6 red marbles + 2 white marbles + 5 blue marbles = 13 marbles
P (red) = red / total = 6/13
We then put the marble bad so there are still 13 marbles in the bag
P(blue) = blue /total = 5/13
P (red then blue ) = P(red) *P(blue)
= 6/13 * 5/13 = 30/169
Answer and Explanation:
<em>Solving 3x + 2y = 9 for y gives y = -(3/2)x + (9/2).
</em>
You could expect about 1,248 students to play at least 4 hours every week.
Our tables have 100 students involved. All but 4 of the students are in the category of at least 4 hours. That is 96%.
Therefore, we simply need to multiply 0.96 by 1300 to get the estimated amount.
0.96 x 1300 = 1248
