Incomplete Question (See Complete Question Below)

A bag contains 10 red marbles and 15 green marbles.If Yuki selects a marble from the bag without looking, what is the probability that she will pull a red marble?

A-1/5

B-2/5

C-1/2

Answer:

The probability of pulling a red marble is \frac{2}{5}

Step-by-step explanation:

Given

Red Marble = 10

Green Marble = 15

Required

The probability of picking a red marble

First, the total number of marble has to be calculated

Total = Red Marble + Green Marble

Total = 10 marbles + 15 marbles

Total = 25 marbles

The probability of an event is often calculated by dividing the number of required outcomes by the number of possible outcomes.

In this case, the probability of pulling a red marble is calculated as follows:

P(R) = \frac{n(R)}{T}

Where P(R) represents probability of pulling a red marble

n(R) represents number of red marbles

n(R) = 10

T represents total number of marbles

T = 25

By substitution,

P(R) = \frac{n(R)}{T} becomes

P(R) = \frac{10}{25}

Reduce fraction to lowest term by dividing the numerator and denominator by 5

P(R) = \frac{2}{5}

Hence, the probability of pulling a red marble is \frac{2}{5}

<span>If you're trying to solve for x, then there is no solution. Since the left side is positive, the inequality has no solution over the domain.</span>
