Answer: probability of Jake took 2 reds marbles = 3/52
probability of John took 1 blue marble = 1/8
Step-by-step explanation:
Okay, I will assume in this problem that the sample is not replacement, which means after Jake took 2 marbles, he didn't put it back into the sample.
The total of the sample = 20 + 10 +5 +5
Probability of Jake took the 1st red marble is 10/40 because there are 10 marbles in a whole bag of 40 marbles. Once Jack picked the 1st red marble out, there are only 9 red marbles left, thus the probability of the 2nd red marble is 9/39.
=> probability of Jake took 2 reds marbles = (10/40) *(9/39) = 3/52
and it goes the same way for John, except we only need to find 1 blue marble so we don't have to multiply anything here.
=> probability of John took 1 blue marble = 5/40 = 1/8
Answer:
k(3n) = 9n² + 9n
General Formulas and Concepts:
Order of Operations: BPEMDAS
- Substitution and evaluation
Step-by-step explanation:
<u>Step 1: Define</u>
k(n) = n² + 3n
k(3n) is n = 3n
<u>Step 2: Solve</u>
- Substitute: k(3n) = (3n)² + 3(3n)
- Exponents: k(3n) = 9n² + 3(3n)
- Multiply: k(3n) = 9n² + 9n
