Answer:
Im not sure but i did 5x9=45
Step-by-step explanation:
Answer:
I know you said relevant so i have two answers.
1) (not so relevant).
You could use it to show how NASA and astronomers use it to calculate the distance between planets and connect it to building rockets and all that cool stuff.
2) (relevant).
For the one about music, you could connect it to sound engineers and use sine and cosine graphs to calculate wavelengths
Use combination
probability = (11C1 + 7C1)/28C2
probability = (11+7)/378
probability = 18/378
probability = 1/21
2 x 9 = 18 so 5 x 9 = 45 so for every 18 gray chips there are 45 pink chips. Also 2/5 is equivalent to 18/45
