Answer:
I think its 336. I might be wrong though, But I hope I am right.
Step-by-step explanation:
The answer is this: $3.60
4 x 10 = 40 - 0.4 = 3.6
So x + y = 45, and 4x + 5y = 195. Get y by itself. Subtract x from both sides in the first equation to get y = 45 -x, and subtract 4x from the second equation to get 5y = 195 - 4x. Divide by 5 to both sides to get y = 39 - 4/5x. 39 - 4/5x = 45 - x. Add x to both sides to get 39 - 1/5x = 45. Subtract 39 from both sides to get -1/5x = 6. Divide by -1/5 to get x = -30, or 30. In the first equation, do 30 + y = 45. Subtract 30 from both sides to get y = 15. Check. 4(30) + 15(5) = 195, or 120 + 75 = 195.
Answer:
The probability that each player will receive three picture cards = 0.0324
Step-by-step explanation:
As given,
A deck of 52 cards contains 12 picture cards
Remaining card = 52 - 12 = 40
So,
Total number of ways in which 12 picture card is distributed =
Now,
The Total number of ways in which Remaining cards are distributed =
So,
Total number of ways of getting 3 picture card and remaining card = ×
=
Now,
Total number of ways to distribute 52 cards so that each people get 13 card =
∴ The probability =
= ×
= ×
= ×
= ×
= 0.0324
∴ we get
The probability that each player will receive three picture cards = 0.0324
