One bag of marbles contains 2 black , 3 red , and 5 white marbles . A second bag contains 3 white and 2 black marbles . What is

BaLLatris [955]

Answer:

NOT BOTH BLACK = 1-2/25 = 23/25

Step-by-step explanation:

Bag 1 : 8 non-black out of 10

P(1) = 8/10

Bag 2: 3 non-black out of 10

P(2)=3/5

Probability of both independent events happening can be calculated using the multiplication rule

P(1) and P(2) = P(1)*P(2) = 8/10 * 3/5 = 24/50 = 12/25 (both are not black, or none is black)

Interpretating not both black meaning at most one black, then

we calculate the probability of both are black,

P(1) = 2/10

P(2) = 2/5

Probability that both balls are black can be calculated using the multiplication rule

P(1) and P(2) = 2/10 * 2/5 = 2/25

Probability that NOT BOTH BLACK = 1-2/25 = 23/25, i.e. at most one black

Need help please 4x + Y = 1 , x + 2y = 9 rewrite equation into slope intercept form (y=mx+b)

Nesterboy [21]

Answer:

Given and Explained Below.

Step-by-step explanation:

slope intercept form: y = mx + b ............where m is slope and b is y-intercept

1st question:

4x + y = 1

y = 1 - 4x

y = -4x + 1

2nd question:

x + 2y = 9

2y = 9 -x

y = (-x + 9)/2

y = $-\frac{1}{2}x + 4.5$

Mathew buys a single ticket for $8 out of a lottery of 1000 tickets where the prize for the one winning is to be $800. How much

miss Akunina [59]

Given:

The number of tickets = 1000

Mathew buys a single ticket for $8

Winning price = $800

To find:

The expected earning per ticket.

Solution:

It is given that the total number of tickets is 1000. So, the probability of winning is:

$P(Winning)=\dfrac{1}{1000}$

The probability of losing is:

$P(losing)=\dfrac{999}{1000}$

The expected earning per ticket is:

$E(x)=800\times P(Winning)-8\times P(losing)$

$E(x)=800\times \dfrac{1}{1000}-8\times \dfrac{999}{1000}$

$E(x)=\dfrac{800}{1000}-\dfrac{7992}{1000}$

$E(x)=\dfrac{800-7992}{1000}$

$E(x)=\dfrac{-7192}{1000}$

$E(x)=-7.192$

Therefore, the expected earning per ticket is -7.192. Here, negative sign means loss of $7.192.
