Answer:
4/27
Step-by-step explanation:
6 red marbles, 8 blue marbles and 4 yellow marbles.= 18 total marbles
P(red marble) = number red marbles / total
=6/18 = 1/3
We put the marble back
6 red marbles, 8 blue marbles and 4 yellow marbles.= 18 total marbles
P(blue marble) = number blue marbles / total
=8/18 = 4/9
P(red, replace. blue) = P(red) * P (blue)
= 1/3 * 4/9 = 4/27
Answer:
Joseph's present age=3 yrs
David's present age=9 yrs
Step-by-step explanation:
Let Joseph's present age be x.
David's present age=3x
__________________
Ater 3 yrs,
Joseph's age=x+3
David's age=2(x+3)
Also, we can add 3 to David's present age to get age After 3 yrs. So, David's age after 3 yrs would also be 3x+3.
Now, balance them.
3x+3=2(x+3)
3x+3=2x+6
x=3
D"s prsent age=9
J's present age=3
