Can anyone solve this correctly?

180ft³

Step-by-step explanation:

We know that to find volume we do base × length × height, so just multiply 5 by 12 by 6, and you would get 360, but the pool is halfway filled, so the answer would be 180.

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

expression #3 is not equivalent. the others are.
