Answer:A)0.27
B)0.78
Step-by-step explanation:
This is the probability of picking 2balls of same color.
P(RR)+Pr(WW)+Pr(BB)
3/10×2/9+4/10× 3/10+3/10 ×2/9=6/90+12/90+6/90=
24/90=4/15=0.27
B)if the first ball is not returned, then there are 9 balls left.
Then probability of same color will be
PrB+PrW+PrR
2/9+3/9+2/9=
7/9=0.78
