Answer:
A
Step-by-step explanation:
Answer:
8/13
Step-by-step explanation:
In a standard deck there are 52 cards. Let A denote the event of drawing a black card and B denote the event of drawing face card. We have to find P(A or B) or P(A∪B).
P(A∪B)=P(A)+P(B)-P(A∩B)
There are 26 black cards in a standard deck so,
P(A)=26/52.
There are 12 face cards in a standard deck so,
P(B)=12/52.
There are 6 cards that are black face cards.
P(A∩B)=6/52.
P(A∪B)=P(A)+P(B)-P(A∩B)
P(A∪B)=26/52+12/52-6/52
P(A∪B)=38/52-6/52
P(A∪B)=32/52
P(A∪B)=8/13
Thus, probability of drawing a black card or a face card is 8/13.

0.16 —> 4/25
Answer:
Option A and D
Step-by-step explanation:
<u>Step 1: Determine which options are true</u>
<em>Option A is correct because the range is always 3, the graph never moves.</em>
Option B is incorrect because into order to be a function, there has to be only one y per x. Not one x per y.
Option C is incorrect because this line only stays at 3.
<em>Option D is correct because the domain goes both to positive infinity and negative infinity.</em>
Option E is incorrect because the domain is all real numbers.
Answer: Option A and D
