Answer:
2/9
Step-by-step explanation:
lets create a sample space
so
the pirates can be sold for $7 $6 or $9
p
6 7 9
under the sea can be sold for $6 $7 or $9
S
6, 7, 9
driving test can be sold for $6 $7 or $9
D
6, 7, 9
here are all the combinations:
p,6
p,7
p,9
s,6
s,7
s,9
d,6
d,7
d,9
since out of 9 combinations driving test is the only one that is not water related lets look at that. There are only 2 combinations of driving test which are less than or equal to $7, (d,7 and d,6) hence the probability of selling no water games for less than $7 is 2/9
Answer: 149,150,151
Step-by-step explanation:
1.st solution
Let the smallest number is x.
So next consecutive number is x+1
So the third consecutive number is x+2
So the sum of these three numbers is:
x+x+1+x+2=450
3x+3=450
3x=447
x=149 - first number
Second number is 149+1=150
Third number is 150+1=151
2-nd solution
The sum of 3 numbers in row is 450. It means that average number is 450:3=150 - is the number which is in the middle
So the first one number is 150-1=149 and the third number is 150+1=151
So you have 328 lemons at first right?
And you gave 246 to your neighbor right?
That means you have to takeaway 246 from 328 right?
So 328-246 is 82 ok?
So you have 82 lemons left
Answer: it has a 20% increase
