Answer:
The probability is 1/18.
Step-by-step explanation:
There are 10 balls in total. Let's start with the probability of just the green. There is 1 green ball.out of 10 balls total, so the probability of pickin just the green one would be 1/10. Since we aren't replacing the balls after we choose them, the total number of balls is now 9. now the probability of picking one yellow ball out of the nine balls left is 5/9 because there are 5 yellow balls. To get the probability of the green and yellow balls picked, we multiply the individual probabilities to get the actual probability of choosinf one green and one yellow ball without replacement. So multiply 1/10×5/9= 5/90, simplified to 1/18.
If Jesus can walk on water and watermelons are 92 percent water, if I can walk on watermelons, does that make me 92 percent Jesus?
Call the number of hours babysitting
and the number of hours walking dogs
.
We know that she earns $6/hr for babysitting or
, and $5/hr walking dogs or
. We also know the total money is $43 and the total time is 8hours. Therefore:
To solve: First rearrange equation 1 to solve for either
or
(doesn't matter which, I'll use
):
Now substitute into equation 2:
and solve for
Now backsubstitute to solve for
:
She babysat for 3 hours and walked dogs for 5.
