In an experiment, there are n independent trials. For each trial, there are three outcomes, A, B, and C. For each trial, the pro

bability of outcome A is 0.80; the probability of outcome B is 0.10; and the probability of outcome C is 0.10. Suppose there are 10 trials.
Can we use the binomial experiment model to determine the probability of four outcomes of type A, five of type B, and one of type C? Explain.

(A) Yes. A binomial probability model applies to three outcomes per trial.
(B) No. A binomial probability model applies to only two outcomes per trial.
(C) Yes. Each outcome has a probability of success and failure.
(D) No. A binomial probability model applies to only one outcome per trial.

Answer:

(B) No. A binomial probability model applies to only two outcomes per trial.

Step-by-step explanation:

The binomial probability is the probability of having x sucesses on n repeated trials of an experiment that can only have two outcomes. This is why it is called the binomial probability.

Since in our problem there are three possible outcomes, the binomial probability cannot be used.

The correct answer is (B)

(B) No. A binomial probability model applies to only two outcomes per trial.

Answer:

given \:  \\ \\ e = 3f \\  e + f = 48 \\  \\ 3f + f = 48 \\   4f = 48 \\ f =  \frac{48}{4}  \\ f = 12 \\ so. \\ e = 3 \times 12 = 36

Emily is solving the equation 2(x+9)=4(x+7)+2 where did she make an error
Wittaler [7]
Hello!

2(x + 9) = 4(x + 7) + 2

Distribute the 2

2x + 18 = 4(x + 7) + 2

Distribute the 4

2x + 18 = 4x + 28 + 2

Combine like terms

2x + 18 = 4x + 30

Subtract 18 from both sides

2x = 4x + 12

Subtract 4x from both sides

-2x = 12

Divide both sides by -2

x = -6

Where she did something different than me is her mistake

Hope this helps!

Ax-by/c =d solve for x
wolverine [178]
Answer: x = (cd + by) / a

Working out:

(ax - by) / c = d

1)Multiply by c on both sides to get:
ax - by = cd

2) Add by on both sides to get:
ax = cd + by

3) divide by a on both sides to get:
x = (cd + by) / a
