It’s either just 2xy or it’s 2xy(x+2)(x-4)
The jar has 6+5=11 marbles.
We have to find the probability of the following event:
1.We pick a marble from a jar that has 11 marbles in total, 5 of them are red
2.We pick a marble from a jar that has now 10 marbles in total, 4 of them are red (because in the previous step we picked a red marble and did not put it back in the jar)
The probability of the first event is:

The probability of the second event is:

The probability of the both events to happen is:

Answer:
x = 65
Step-by-step explanation:
The sum of exterior angles of a polygon is 360°.
40 + x + 77 + 2x + 45 = 360
3x + 165 = 360 . . . . simplify
x + 55 = 120 . . . . . . divide by 3
x = 65 . . . . . . . . . . . subtract 55
6/10 x 10/1 = 60/10
Which equals 6
