Answers

Answer 1
Answer: 48.75 / 750 = 0.065
0.065 * 100% = 6.5%

Check:
750 * 6.5% = 750 * 6.5/100 = 750 * 65/1000 = 48750/1000 = 48.75
Answer 2
Answer:

Answer:

6.5%

A marble is randomly selected from a bag containing 3 Red marbles, 3 Blue marbles, and 3 Green marbles. What is the probability that the selected marble is Green?A) 3

B) 1/3

C) 1/9

D) 1/2

Answers

The probability that the selected marble is Green for the considered case is given by: Option B: 1/3

How to calculate the probability of an event?

Suppose that there are finite elementaryevents in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

P(E) = \frac{\text{Number of favorable cases}}{\text{Number of total cases}} = (n(E))/(n(S))

where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.

Given that:

  • Bag has 3 green, 3 red, and 3 blue marbles.
  • A marble is selected at random.

To find: P(selected marble is green)

Take:

E = event that a marble selected at random is green.

Numbre of cases in which E can be done is 3 (as there are 3 green marbles).

Number of total cases = 3+3+3 = 9 (total 9 marbles, each can come as an outcome).

Thus, we get:
P(E) = \frac{\text{Number of favorable cases}}{\text{Number of total cases}} = (n(E))/(n(S)) = (3)/(9) = 1/3

Thus, the probability that the selected marble is Green for the considered case is given by: Option B: 1/3
