Answer:
0.33
Step-by-step explanation:
We would like to find the probability that both beads are aqua.
There are 6 aqua beads. Let's calculate the number of ways we can select 2 aqua beads from these 6. We use combinations, which is , where the n! means n * (n - 1) * (n - 2) * ... * 2 * 1.
The value of the expression is:
So there are 15 ways to choose 2 aqua beads.
Now let's calculate the number of ways we can select any 2 beads. There are 6 + 4 = 10 beads in total, so we do the same thing as before using combinations:
Our fraction is thus:
15 / 45 = 1/3 ≈ 0.33
The answer is thus 0.33.

Answer:
x <
Step-by-step explanation:
distribute the parenthesis on the right side
5x + 3 < 3x + 6 ( subtract 3x from both sides )
2x + 3 < 6 ( subtract 3 from both sides )
2x < 3 ( divide both sides by 2 )
x <
Number of salmon in lake is 360 salmon
<u>Given</u>:
Total number of fish released = 72 salmon
Number of salmon catch with tag = 20%
<u>Find:</u>
Number of salmon in lake
<u>Computation:</u>
Number of salmon in lake = Total number of fish released / Number of salmon catch with tag
Number of salmon in lake = 72 / 20%
Number of salmon in lake = 72 / 0.2
Number of salmon in lake = 360 salmon
