Answer:
1/15
Step-by-step explanation:
First you must figure out your total outcomes, int the problem it said ten. Than take the number of students and put the number of students over the number of outcomes. This will tell you the probability of drawing one student. Next you must subtract 1 student and one member from your original equation. This is because you have assumed that the first drawing had a favorable outcome. So that leaves you with 2/9. Next you must multiply both the first fraction (3/10) and the second fraction (2/9) to come up with the total probability of the event occurring.

When x = 3,
-3x = -3(3) = -9

Answer:
The estimated amount earned by band each day is $107.
Step-by-step explanation:
Let the amount Hey band earned each night = $k
Now, the band played for 3 nights.
So, the amount earned in 3 days = 3 x ( amount earned each day)
= 3 x $k = $3k
Also, the band earned an amount of $321 in 3 days.
⇒$3k = $321
or, k = 321/3
⇒ k = 107
Hence the estimated amount earned by band each day is $107.
