Answer:
See below.
Step-by-step explanation:
1.
PM as the number or rows not equal to coloumn
2.
1*2 as MN = ( 32 )
( 61 )
3.
= ( 4x2+7x4 4x3+7x8 4x9+7x1)
=(36 68 43)
To solve number eight, you would set it up as an equation equal to 180
72+7x+24=180
Next you would combine like terms 24 and 72 to get 96
Now the equation is 96+7x=180 Now, subtract 96 from 180 and then divide by seven to get x, so then x is equal to 12
2 yellow marbles, 7 red marbles, 1 green marble.....total of 10 marbles
probability of first picking a yellow marble : 2/10 reduces to 1/5
replacing the marble
probability of picking another yellow marble : 2/10 reduces to 1/5
probability of both is : 1/5 * 1/5 = 1/25 <==
