I have these questions, would someone mind answering them?

1a) 0.03 = 3/100 = 3%

2b) 0.08 = 8/100 = 8%

3c) 0.4 = 4/100 =4%

4d) 3/90

5e) 4/90

Step-by-step explanation:

a, b, c we multiply the probability of each one green = 1/10  red = 3/10 blue = 4/10 yellow = 2/10

They are independant and they are replaced.

2a ) they are dependent as they are not replaced so before multiplying we see the total is reduced each turn. From 1/10 to 3/9 for green and red.

They mention independent as they stay independent per 2 picks.

Meaning red is dependant on green but yellow is not dependant on when we pick for red its only dependant for blue.

1 x 3 = 3 10x 9 = 90 = 3/90  green and red

2 x 4  = 8  10 x 9 = 90  = 4/90

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
