Please help me with this question. Thanks!

Assuming that all the grapes have the same probability of being randomly picked:

  • a) 0.11
  • b)  0.24

<h3>How to find the probabilities?</h3>

We know that there are 8 green grapes and 15 red grapes on the bowl, so there is a total of 23 grapes.

a) Here we need to find the probability that both grapes are green. Remember that the probability of getting a green grape is equal to the quotient between the number of green grapes and the total number of grapes, this is:

P = 8/23

But then he must take another, because he already took one, the number of green grapes is 7, and the total number of grapes is 22, so for the second grape the probability is:

P' = 7/22.

The joint probability is the product of the two individual probabilities:

prob = (8/23)*(7/22) = 0.11

b) For the first green grape we know that the probability is:

P = 8/23

Then he must get a red grape. There are 15 red grapes and 22 grapes in total, so the probability is:

P' = 15/22

Then the joint probability is:

prob = (8/23)*(15/22) = 0.24

Determine whether the events E and F are independent or dependent. Justify your answer. ​(a) ​E: A person living at least 70 yea
Gnoma [55]

Answer:

a) E & F are dependent because regularly handling venomous snakes can affect the probability of a person living at least 70 years.

Step-by-step explanation:

Independent Events. When two events are said to be independent of each other, what this means is that the probability that one event occurs in no way affects the probability of the other event occurring.

Two events are dependent if the outcome or occurrence of the first affects the outcome or occurrence of the second so that the probability is changed.

Since Venomous snakes are species of the suborder Serpents that are capable of producing venom, which they use for killing prey, for defense, and to assist with digestion of their prey and the older you get the less active you become, Hence the handle of venomous snakes can affect the probability of a person living at least 70 years
