Answer: here you go

Step-by-step explanation:

1st probability: green first then blue second: 6/10*4/9 = 24/90 or about 0.27

2nd probability: blue first then green second: 4/10*6/9 = same as first answer (about 0.27)

Each and every probability was found using probability theory.

Number of blue balls = 4

Number of green balls =6

Total number of balls =10

What is probability?

Probability is the measure of the likelihood of occurrences.

A) Without replacement:

P(green first) = 6/10

Number of balls left =9

Number of blue balls =4

So, P(blue second) = 4/9

Total probability = 6/10 * 4/9 = 4/15

P(blue first) = 4/10

Number of balls left =9

Number of green balls =6

So, P(blue second) = 6/9

Total probability = 4/10 * 6/9 = 4/15

B) With replacement:

P(blue first) =4/10

Number of balls left =10

Number of green balls = 6

So,  P(green second) = 6/10

Total probability = 4/10 * 6/10 = 6/25

P(green first) =6/10

Number of balls left =10

Number of blue balls = 4

So,  P(green second) = 4/10

Total probability = 6/10 * 4/10 = 6/25

Thus, each and every probability was found using probability theory.
