At total of 2 feet of snow falls over three days on the first day 1/6 of the snow falls on the second day 7/12 of the snow falls
ioda

Answer:

Day\ 3 = 1\frac{3}{12}

Step-by-step explanation:

Given

Total = 2ft

Day\ 1 = \frac{1}{6}

Day\ 2 = \frac{7}{12}

Required

Determine the amount of snow on day 3

This can be calculated using:

Day\ 1 + Day\ 2 + Day\ 3 = Total

Substitute values for the known parameters

\frac{1}{6} + \frac{7}{12} + Day\ 3 = 2

Collect Like Terms

Day\ 3 = 2 - \frac{1}{6} - \frac{7}{12}

Take LCM

Day\ 3 = \frac{24 - 2 - 7}{12}

Day\ 3 = \frac{15}{12}

Express as mixed number

Day\ 3 = 1\frac{3}{12}

Determine whether the pair of actions results in independent or dependent events. Serena picks one marble out of a bag. Then, af
harina [27]

Answer:

B) Independent; the 1st marble selection will not affect the 2nd marble selection.

Step-by-step explanation:

When finding the probability of events in mathematics, we have both independent and dependent events.

Independent events are events that occur when the results of selection of the first events does not affect the results or outcomes of the second events.

Dependent events are the opposite of Independent events. They are events that occur when the results or outcomes obtained from the second events is affected by the results or outcomes from the selection of the first events.

From the question, we can see that the first event is she picked one marble from the bag. The second event is she replaced the marble before picking another marble. By doing this, the total number of possible outcomes for the probabilities of both events remains the same and they are unaffected.

Therefore, we can say that the two events are Independent because the 1st marble selection will not affect the 2nd marble selection.
