Answer:The answer is 50
Step-by-step explanation:
The first step is to add up the numbers in order to get the outcome
5 red + 20 blue +25 green =5+20+25 =50
Step 2
Probability =no of events /no of outcome
We were asked to find the probability of red
Where red represent event
And the summation of red ,green and blue represents outcome .
So probability of red =5/50 = 1/10
Step 3
Recall in the question ,we were told that the card was selected 500 times ,so we multiply the probability of getting red by 500
1/10 *500 =50
Therefore the probability of drawing a red card from the special deck 500 times is 50 .
Answer: A and B
Explanation: I’ll use A as an example. When you multiply the bottom equation by -3/2, the equation becomes: -9x+6y=-3. Then, proceed to add the equations. Look at X and Y in both equations: do the Y variables in both equations equal to 0 when added together? Yes, because -6y+6y=0! Therefore, you can eliminate y in these two equations.
Hope that’s helps シ
