= x^{3} -3x^{2} -4x^{} +3x^{2} -9x^{} -12

melisa1 [442]

Answer:

Step-by-step explanation:

6x^2+4x-42

2(3x^2+2x-21)=0

PLSS HELP ASAP
Mama L [17]

based on the number of marbles in the bag, the number of marble groups possible is 7,140 groups.

the probability of selecting 2 red and 1 yellow is 1/68.

<h3>what number of 3-marble groups can be made?</h3>

first, find the number of marbles:

= 7 + 8 + 9 + 7 + 5

= 36

the number of marble groups are:

= 36 ! / (3 ! x 33 !)

= 7,140 groups

the probability of picking 2 red and 1 yellow is:

= (( (7! / (2! x 5!)) x ( ( 5! / (1! x 4!))) / 7,140

= 1 / 68

= 1.47%
