A bag contains 3 red marbles and 4 blue marbles.

vazorg [7]

The probability of getting two marbles of the same colour is 25/49.

<h3>What is defined as the probability?</h3>

Probability is simply the likelihood of something occurring. When we are uncertain about the outcome of an event, we can discuss the probabilities of various outcomes—how likely they are.
Statistics is the study of events governed by probability.

The formula for finding the probability is;

Probability(event) = favourable outcome/total outcome

Total red marbles in the bag = 3.

Total blue marbles in the bag = 4.

Total marbles = 7.

As, the case is with replacement total marble will remain same after the drawn of first marble.

The probability that first marble be red = 3/7

The probability that first marble be red = 3/7

The combine probability getting red marble = 3/7 × 3/7 = 9/49

The probability that first marble be blue = 4/7

The probability that first marble be blue = 4/7

The combine probability getting blue marble = 4/7 × 4/7 = 16/49.

The condition for OR either red or blue marble be drawn.

Thus,

The combine probability getting marble of same colour = 9/49 + 16/49.

Therefore, the combine probability getting marble of same colour = 25/49.

Maria wraps the gift she is taking to a friend’s birthday party. She doesn’t have much paper, so she does not overlap any of the

Elina [12.6K]

Answer:

Total paper required to wrap the gift without any overlaps: $2700\ cm^{2}$

Step-by-step explanation:

Here, we need to find the total paper required without any sides overlapping to wrap the gift.

The gift is of <em>cuboid </em>type.

Given the following:

<em>Length </em>= 15 cm

<em>Width </em>= 30 cm

<em>Height </em>= 20 cm

Please refer to the attached figure.

We can infer that to find the paper required, we actually need to the find the<em> total surface area of the cuboid</em>.

Because the gift wrap will be done <em>on the faces of gift</em> (which is of cuboid shape).

Formula for Surface Area of <em>Cuboid:</em>

$\text {Area = } 2 \times (\text{Length}\times \text{Width} + \text{Width}\times \text{Height} + \text{Length}\times \text{Height} )\\\\\Rightarrow 2 \times (15 \times 30 + 30 \times 20 + 15 \times 20)\\\Rightarrow 2 \times (450 + 600 + 300)\\\Rightarrow 2 \times (1350)\\\Rightarrow 2700 cm^{2}$

Hence, total paper required to wrap the gift without any overlaps: $2700 cm^{2}$
