If a bag of balloons consists of 47 white balloons, 5 yellow balloons, and 10 black balloons, what is the probability that a balloon chosen randonly from the bag will be black?

10/62, 5/31,  or 16.129%

Step-by-step explanation:

First you have to add all of the balloon colors together to get the entire sample size.

47 + 5 + 10 = 62

Next, you need to know the how many of the balloon colors you what the probabilty for that are in the sample size.

10 black balloons.

Finally, you divide the number of black balloons by total balloons to find the probability of randomly choosing one.

10/62 = 5/31 or 16.129%

I hope this helps!

step-by-step explanation:

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
