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

Answer:
Karen has only 2 checkers left
Step-by-step explanation:
Jasper has 7 checkers than Karen
Jasper has 9 checkers
The equation can be written as
7 + k = 9
This means that 7 plus Karen checkers equal 9 which is jasper checkers
It can also be written as
9 - 7 = k
k = 2
Therefore Karen has only 2 checkers left
Expression,
