The probability can be calculated as given because there are a total of 52 cards.
<h3>What is probability?</h3>
It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Total number of card = 52
Number of king of heart = 1
P(getting a king of hearts) = 1/52
P(getting a spade) = 13/52 = 1/4
P (getting a 5 or a club) = (16/52) = 4/13
P(getting a 5 or a 7) = 4/52 + 4/52 = 8/52 = 2/13
P(getting a card which is not a spade) = 1 - 1/4 = 3/4
P(getting 11 of clubs) = 1/52
Thus, the probability can be calculated as given because there are a total of 52 cards.

Answer:
Step-by-step explanation:
since -1≤sin2x≤1 no x values would satisfy the equation
Similarities: same atomic number
Differences: they have a different number of neutrons
Answer:
The inequality which represents the graph is y ≤ -2x + 1 ⇒ A
Step-by-step explanation:
To solve the question you must know some facts about inequalities
- If the sign of inequality is ≥ or ≤, then it represents graphically by a solid line
- If the sign of inequality is > or <, then it represents graphically by a dashed line
- If the sign of inequality is > or ≥, then the area of the solutions should be over the line
- If the sign of inequality is < or ≤, then the area of the solutions should be below the line
Let us study the graph and find the correct answer
∵ The line represented the inequality is solid
∴ The sign of inequality is ≥ or ≤
→ That means the answer is A or B
∵ The shaded area is the area of the solutions of the inequality
∵ The shaded area is below the line
∴ The sign of inequality must be ≤
→ That means the correct answer is A
∴ The inequality which represents the graph is y ≤ -2x + 1
Answer:
A is the correct answer
