Answer:
Hence the probability that 1 pair of red socks and 1 black skirt are chosen at random is .
Step-by-step explanation:
Let A denotes the event that 1 pair of red socks are chosen.
Let B denote the event that a 1 black skirt is chosen.
let P denotes the probability of an event. ( Probability of an event is defined as the ratio of Number of favourable outcomes over the total number of outcomes)
and
Hence, the probability that 1 pair of red socks and 1 black skirt are chosen at random i.e. is given by:
(since the events are independent)
Hence,
Answer:
Option B - graphing is the correct answer.
Step-by-step explanation:
To solve a system of inequalities we need graphing. Inequality tells us about the relative size of two values. When we graph the x and y co-ordinates, the solution is not the drawn line, but the area of the coordinate plane that satisfies the inequality. In inequalities, multiple solutions can be possible.
Plug and chug method does not a complete solution, it only tells where a point belongs. Guess and check does not apply here.
