You have 200 dice in a bag. One of the dice has a six on all sides so it will land on a six every time you roll it. The other 19

LiRa [457]

Answer:

Step-by-step explanation:

There are 200 dice out of which 199 are fair

Prob for 6 in one special die = 1 and

Prob for 6 in other die = 1/6

A1- drawing special die and A2 = drawing any other die

A1 and A2 are mutually exclusive and exhaustive

P(A1) = 1/200 and P(A2) = 199/200

B = getting 6

i) Required probability

= P(A1/B) = $\frac{P(A1B)}{P(A1B)+P(A2B)} \\$

P(A1B) = $\frac{1}{200} *1 = \frac{1}{200}$

P(A2B) = $\frac{199}{200}*\frac{1}{6}=\frac{199}{1200}$

P(B) = $\frac{205}{1200} =\frac{41}{240}$

P(A1/B) = $\frac{1/200}{41/240} =\frac{7}{205}$

P(A2/B) = $\frac{199/1200}{41/240} =\frac{199}{205}$

Solve each system of linear equations by substitution x+y=3 -x+y=5

SSSSS [86.1K]

Answer:

x = -1, y = 4

Step-by-step explanation:

x + y = 3

-x + y = 5

This means that y = 3 - x

We can substitute this value into the equation

-x + y = 5

-x + 3 - x = 5

3 - 2x = 5

Subtract 3 from both sides

-2x = 2

Divide both sides by -2

x = -1

Plugging this number into the equation, we have:

-1 + y = 3

Add 1 to both sides

y = 4
