My name is Ann [436]

Answer:

Step-by-step explanation:

Let the number of floors  = x

Number of apartments per floor = 4x

4x *x = 100

4x² = 100

x² = 100/4

x² = 25

x =√25

x = 5

Number of apartments on each floor = 4*5 = 20

You draw a card from a deck. If you get a diamond, you win nothing. You lose $2 if getting a heart. If you got a spade, you win
tino4ka555 [31]

Answer:

Step-by-step explanation:

Let  X = amount you can win at this game (# of dollars you can win)

x = (0, -2, 6, 10, 15)

  • P(X=0) = P(probability of picking a diamond) = 13/52 = .25
  • P(X=-2) = P(probability of picking a heart) = 13/52 = .25
  • P (X= 6) = P(probability of picking a spade) = 13/52 = .25
  • P(X=10) = P(probability of picking a club) = 12/52 ≈ .231
  • P(X=20) = P(probability of picking the ace of clubs) = 1/52 ≈ .019

Probability Distribution of X

x p(X = x) Decimal

0 13/52 0.25

-2 13/52 0.25

6      13/52       0.25

10 12/52 0.231

15 1/52         0.019

Total  52/52   1.00
