If you roll a number cube two times, what is the probability of rolling an even on the first roll and a four on the second roll?
Bad White [126]

Answer:

1/12

Step-by-step explanation:

Probability is a ratio derived as the number of possible outcomes divided by the total outcome.

On a number cube, the even sides are 2, 4 and 6. This means that the possible outcome for rolling an even is 3 while the total outcome is 6. Hence the probability of rolling an even P(E)

= 3/6

The probability of rolling a 4  P(4)

= 1/6 (4 appears on one side)

Hence  the probability of rolling an even on the first roll and a four on the second roll

P(En4) = 3/6 * 1/6

= 3/36

= 1/12

assuming that the DVD player loses 60% of its value every year it is in a video store suppose the initial value of the DVD playe
Alik [6]
The multiplier you would use to find the new value would be 0.4.

The reason for this is that 100%-60% =40%. This is the part of the value it will keep. 40% is the same as 0.4.

This decimal represents the part of the original price that is it still worth.

The multiplier is 0.4 because that it what you would multiply $80 by to find the new value.
