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

Answer 1
Answer:

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

Please help thank you guys

Basically: Whenever you have a number times a variable, you don't have to write the multiplication sign.

5 × n is the same thing as 5n.

Let's write each of these out.
a) 5 + 2 + x
b) 5 + 2x
c) 5 + x + x
d) 5 + x² (the ² means multiply by itself)
e) 5 + 2x (sum = adding together)
f) 5 × 2x (product = multiplying together)

As you can see, only B and E fit the expression given.

The sum 9/10 and 1/32 is less than or greater than 1?

Answers

lets find out! well your trying to find the number that is closest... so lets try.... 160
So , (9)/(10) x 16 = (144)/(160)   and    (1)/(32) x = (5)/(160)
(144)/(160) + (5)/(160) = (149)/(160)
so it is less than 1 
Hope i helped! :D
Less than 1! If you simplify it the sum is less

9.64 rounded to the nearest tenth

Answers

Hello,

9.64 rounded to the nearest tenth is 9.6.

Have A Good Day.
Your answer would be 9.6

.6 is a six tenths.

To help you remember to round up or down remember this rhyme: 5 or more raise the score. 4 or less give it a rest.

9.64 is rounded to the nearest hundredth. To get to the nearest tenth you need to get rid of the four. Since it's less than 5, you just knock it away like it wasn't ever there. If it's 5 or above, you would have to round the number up. If you had to round up it'd be 9.7.

Paul cuts apples into cubes with a height of 1 1 fraction bar 3 in. He then coats the apples in caramel. Hiw much area is covered in caramel

Answers

ok so since we don't know how many cubes are covered, I will solve for how much area was covered on 1 cube
cube has 6 faces, all squares
area of square=side^2
therefor surface area (area covered by carmael)=6 times side^2
side=1 and 1/3
convert 1 and 1/3 to imporoper
1 and 1/3=1+1/3=3/3+1/3=4/3

Surface Area=6 times side^2
SA=6(4/3)^2
SA=6(16/9)
SA=96/9
SA=10 and 6/9
SA=10 and 2/3

answer is 10 and 2/3 in^2 is covered per cube
(if you are given a number of cubes, multiply 10 and 2/3 in^2 by number of cubes)
