Step-by-step explanation:
you had me confused so I had to go in my mathmetics book it was 1/4 not 14 thats what had me confused
Andy to get to Willie's house = 15 ways
Andy to get to Willie's house = 45 ways
<h3>
How to determine the ways</h3>
From the information given, we have that from
Andy's house to Billy's hometown = 3 roads
Billy's hometown to Willies house = 5 ways
To travel from Andy's house to Willies house, we should multiply the number of ways
= 3 × 5
= 15 ways
Dan's ranch to Andy's house = 1 road
To Willie's house = 2 roads
For Andy to get to Willie's house, we have;
= 3 × 15
= 45 ways

Answer:
There are 650 cannonballs
Step-by-step explanation:
If you look closely in the picture, you can see that:
- 1st row has 1 ball
- 2nd row has 4 balls
- 3rd row has 9 balls
- 4th row has 16 balls
etc. etc.
We can see that the number of balls is the square of the row number. There are a total of 12 rows. So, rest of the rows has:
- 5th row has 25 balls
- 6th row has 36 balls
- 7th row has 49 balls
- 8th row has 64 balls
- 9th row has 81 balls
- 10th row has 100 balls
- 11th row has 121 balls
- 12th row has 144 balls
If we add up all those, we get total number of balls:
There are 650 cannonballs
Answer:
100%
Step-by-step explanation:
Use conditional probability:
P(B | A) = P(B and A) / P(A)
P(B | A) = (12/28) / P(A)
We need to find the probability that a student studies art.
P(A or B) = P(A) + P(B) − P(A and B)
24/28 = P(A) + (12+12)/28 − 12/28
P(A) = 12/28
P(B | A) = (12/28) / (12/28)
P(B | A) = 1
What this means is that all of the students who study art also study biology.
