x > 5 represents a line with an open circle at 5 and going indefinitely toward infinity.

<h3>What are inequalities and their types?</h3>

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

Given inequality is  - 3(2x - 5) < 5(2 - x).

- 6x + 15 < 10 - 5x.

- x < - 5.

x > 5 (think of moving x to make it positive).

when a card is drawn from a standard deck of 52 cards, what is the probability of getting a. queen b.a red. c.a queen or a red c
Brut [27]

(a) Probability of getting a queen from a deck of 52 cards = \frac{1}{13}

(b) Probability of getting a red card from a deck of 52 cards = \frac{1}{2}

(c) Probability of getting a queen or a red card from a deck of 52 cards = \frac{7}{13}

<u>Solution:</u>

Given that card is drawn from a standard deck of 52 cards.

Need to determine probability of getting  

(a) queen (b) red (c) a queen or a red card

\text { Probability of an event }=\frac{\text { favorable number of events }}{\text { total number of events }}

<em><u>(a) Calculating probability of getting a queen from a deck of 52 cards </u></em>

Favorable events are getting a queen of spade, heart , diamond or club.

Means number of favorable events = 4

Total events is all possible outcomes from 52 cards  

So Total number of event = 52

\Rightarrow \text { probability of getting a queen }=\frac{4}{52}=\frac{1}{13}

<em><u>(b) Calculating probability of getting a red card from a deck of 52 cards </u></em>

Number of red cards are 13 cards of diamonds and 13 cards of heart = 13+13 =26

So number of favorable event = 26

Total number of event = 52

\Rightarrow \text { probability of getting a red card }=\frac{26}{52}=\frac{1}{2}

<em><u>(c) Calculating probability of getting a queen or red card from a deck of 52 cards </u></em>

Favorable events are 26 red cards + two queens of spade and club. Need to keep in mind that queens of heart and diamond is already considered in 26 red cards.

So number of favorable event = (26+2) = 28

Total number of event = 52

\text { Probability of getting a queen or red card }=\frac{28}{52}=\frac{7}{13}

<em><u>Summarizing the result :</u></em>

(a) Probability of getting a queen from a deck of 52 cards = \frac{1}{13}

(b) Probability of getting a red card from a deck of 52 cards = \frac{1}{2}

(c) Probability of getting a queen or a red card from a deck of 52 cards = \frac{7}{13}
