Answer:

First question:0

Second question:2/15

Step-by-step explanation:

First:

Total of marbles=10

since there is no blue the probability is 0, since black is 3. then prob= number of black/total number of marbles. =3/10

therefore 0*3/10 =0

second:

probability of red is 4/10

since the first marble wasn't returned,the total number of marbles=9

therefore probability if the second red marble is =3/9 =1/3

probability of first marble *probability of second marble

(4/10)*(1/3) =(4/30)= 2/15
