Answer: The required probability is \dfrac{5}{6}

Step-by-step explanation:

Since we have given that

Number of people came into Brad's store = 48

Number of them made a purchase = 40

So, the experimental probability that the next person to come into the store will make a purchase would be

\dfrac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}\\\\=\dfrac{40}{48}\\\\=\dfrac{5}{6}

Hence, the required probability is \dfrac{5}{6}

noname [10]

Answer:

23, 33, and 92

Step-by-step explanation:

If the three numbers are x, y, and z, then:

x + y + z = 148

y = x + 10

z = 4x

Substitute:

x + (x + 10) + (4x) = 148

6x + 10 = 148

6x = 138

x = 23

y = 33

z = 92

Find the expected value of the random variable. Round to the nearest cent unless stated otherwise. Suppose you buy 1 ticket for
QveST [7]

Answer:

Expected Value = - 0.5

Step-by-step explanation:

Expected Value [ E(X) ]  = Σ  {X. Probability (X)} = Σ [ (X).P(X) ]

  • Case 1 : Lottery Won

Probability = 1 / 1000

X Value = 500 - 1 = 499

  • Case 2 : Lottery Lost

Probability =  1 - Probability Winning = 999 / 1000

X Value = -1

  • Expected Value :

(1 / 1000) (499) + (999 / 1000) (-1)

0.499 - 0.999

= - 0.5
