Answer: Intersection of A and B = 2
Step-by-step explanation:
Total cards = 52
Let A is the event of drawing a 6 from the deck, and B is the event of drawing a black playing card from the deck.
Total cards having 6 on them = 4
[There are 4 suits of two different colors red and black.]
Total black playing card =26
Intersection of A and B = Black cards having 6 = 2
hence, Intersection of A and B = 2
Answer:
Theoretical probabilities are the long-run relative frequencies based on an experiment.
Step-by-step explanation:
Relative frequency or experimental probability is calculated from the number of times an event happens, divided by the total number of trials in an actual experiment.
With theoretical probability, you don't experiment. Instead, you use what you know about the situation to determine the probability of an event occurring.
Experimental probability approaches theoretical probability when the number of trials is extremely large.
Therefore, theoretical probabilities are the long-run relative frequencies based on an experiment.
Answer:
x=-12
Step-by-step explanation:
First subtract 2x on both sides. and you'll have x+5=-7.
Second subtract 5 on both sides, it will equal you x=-12
Hello!
0.5 (5 - 7x) = 8 - (4x+6)
2.5 - 3.5x = 8 - 4x + 6
2.5 - 3.5x = 2 - 4x
-3.5x + 4x = 2 - 2.5
0.5x = -0.5
X = -1
Your answer is x = -1. I hope this helps!
Answer:
$40
Step-by-step explanation:
Brian starts at $100, then loses 1/4th of the money,
100/4 = 25,
then you subtract 25 from 100, which gives you 75
With the remaining $75, he spends $15 on girl scout cookies,
75 - 15 = 60
He then has $60 remaining, but while walking home, loses 1/3 of the total amount.
60/3 = 20,
you then subtract 20 from 60, which gives you 40
Therefore, $40 is what is remaining.
