2x/x will equal 2.
x/x is in a ratio of one to one
If, for instance, x is equal to 1235324...
2(1235324)/1235324)
2470648/1235324
2
Answer:
207
Step-by-step explanation:
1. False. 0 does not equal to 6. No answers.
2. False. x=0 means the answer is 0.
3. True.
4. False. 2 does not equal -2. No answers.
5. True.
Code: (6*6*6)-(3*3)=207
The first card's probability is easy to calculate.
Of the 52 cards, 26 are black, so the probability is
(26 out of 52) or (1 out of 2) or .5
The second card will be drawn from 51 cards of which 25 are black:
25 / 51
Continuing with this pattern, drawing the 3rd card, the probability is
24 / 50
For the 4th card 23 / 49
For the 5th card 22 / 48
For the 6th card 21 / 47
So, to get the probability of drawing all six cards AND getting all black, we multiply these 6 fractions:
probability = (26 / 52) * (25 / 51) * (24 / 50) * (23 / 49) * (22 / 48) * (21 / 47)
