Conditional probability means that the action is subject to a condition, that it can only happen if some condition is met. So D is the answer. None of the others imposes any condition being met.

Answer:

Option 4 - (Probability of hitting a home run, given that you didn't strike out) is a conditional probability.

Step-by-step explanation:

Conditional probability -

The probability of event A under the condition of event B.

or, it is a measure of probability of an event given that the another event has occurred.

1) Probability of getting an A on a test - No other event happen in this case therefore, it is not a conditional probability.

2) Probability of drawing a club from a deck of 52 cards - No other event happen in this case therefore, it is not a conditional probability.

3) Probability of hitting a home run - No other event happen in this case therefore, it is not a conditional probability.

4) Probability of hitting a home run, given that you didn't strike out- It is a conditional probability because event (hitting a home run) is happened under the condition that you didn't strike out. (By definition)

Therefore, option 4 is the example of conditional probability.

2x + y =8 and 4x -2y = 6

irakobra [83]

Answer:

x=1.25 and y=-5.5

Step-by-step explanation:

2x+y=-8, 2x=-y-8 or 4x=-2y-16. Plug this value in the second equation, we have - 2y-16-2y=6, y=-5.5. Plugging this in any equation we have, x=1.25

bonnie runs 1 2/3 times as far as john each day if bonnie runs 5 miles on monday 3 1/2 miles on tuesday and 5 3/4 miles on wedne

nignag [31]

Answer:

3 miles on Monday

2¹/₁₀ miles on Tuesday

3⁹/₂₀ miles on Wednesday

Step-by-step explanation:

We are told that Bonnie runs 1⅔ (⁵/₃) times as far as John each day

This means that John runs ³/₅ times as far as Bonnie.

MONDAY:

Bonnie runs 5 miles on Monday, therefore, John runs:

³/₅ * 5 = 3 miles

TUESDAY:

Bonnie runs 3½ (⁷/₂) miles on Tuesday, therefore, John runs:

³/₅ * ⁷/₂ = ²¹/₁₀ = 2¹/₁₀ miles

WEDNESDAY:

Bonnie runs 5³/₄ (²³/₄) miles on Wednesday, therefore, John runs:

³/₅ * ²³/₄ = ⁶⁹/₂₀ = 3⁹/₂₀ miles

Find the missing value 8- = -5

podryga [215]

Answer:

x = 13

Step-by-step explanation:

call the missing number x

8 - x = - 5 Subtract 8 from both sides

8-8 - x = -5-8 Combine

-x = - 13 Multiply by -1

x = 13
