A box contains different-colored marbles. If P(blue) = 1, P(green) = 4, and P(blue and green) = 12, which state
riadik2000 [5.3K]

Answer:

Not 100 percent sure but i think the correct answer is the last one.

Step-by-step explanation:

I know that the answer is either the last one or before the last because they are dependent on each other. This is because the probability of both increases when they are added together. The more you have the more likely to get one of them. I went for the last one because i think that the value of together is greater than when they are added.

Again, not 100 percent sure, tried to give it my best shot.

Hope this helps.

Customers are used to evaluate preliminary product designs. In the past, 95% of highly successful products received good reviews
Andrej [43]

Answer: The required probability is 0.615.

Step-by-step explanation:

Let A be the event that a product receives good reviews.

Let E₁ be the event that the product is highly successful.

Let E₂ be the event that the product is moderately successful.

Let E₃ be the event that the product is poor.

P(E_1)=0.40\\\\P(E_2)=0.35\\\\P(E_3)=0.25\\\\P(A|E_1)=0.95\\\\P(A|E_2)=0.60\\\\P(A|E_3)=0.10

(a) What is the probability that a product attains a good review.

So, it becomes,

P(A)=P(E_1)P(A|E_1)+P(E_2)P(A|E_2)+P(E_3)P(A|E_3)\\\\P(A)=0.4\times 0.95+0.0.35\times 0.6+0.25\times 0.1\\\\P(A)=0.615

Hence, the required probability is 0.615.

The ratio of petunias to geraniums in the greenhouse was 15 to 2. The combined numbernof petunias and geraniums was 1020.
AnnZ [28]

Answer:

E. 120

Step-by-step explanation:

Let's say the number of total flowers is (15+2)x

That means the number of geraniums is 2x.

That also means that 1020 = 17x, which makes x = 60

Because 2x = geraniums and x = 60, the number of geraniums is 120
