<h3>
Answer: 9/100</h3>
========================================================
Explanation:
There are 3 pink marbles out of 10 total (we can see that 2 yellow + 3 pink + 5 blue = 10 total)
The fraction 3/10 represents the probability of pulling out a pink marble at random. Since the first one is put back, this means the fraction 3/10 stays the same on the second draw as well.
We use the idea mentioned in the hint to multiply the fractions:
(3/10)*(3/10) = (3*3)/(10*10) = 9/100
The probability of pulling two pink marbles in a row is 9/100, where the first marble is put back.
Effectively, if you were given 100 tries at doing this, you should expect about 9 of those times you get 2 pink marbles in a row.
12÷20=0.6
0.6=60%
550×60%=330
The answer is 330

A rate is common.
Lets find something that isn't constant.
The speed a runner can't be constant
Perhaps they run for 1 hour and get 1 mile done, and the other hour, they run 1.3 miles in 1 hour.
