What is the probability that the first marble is blue and the second is green? Write your answer as a fraction in simplest form. Plz help please help me

8/45

Step-by-step explanation:

Step one:

Given

sample space

4 are green,

2 are red, and

4 are blue.

Sample size= 4+2+4= 10

Step two:

Since the event of choosing marbles is done without replacement

The first choice is

Pr(blue)= 4/10= 2/5

The second choice= 4/9

hence the probability is

= 2/5*4/9

=8/45
