June rolls a fair dice 132 times. How many times would June expect to roll an even number?

66

Step-by-step explanation:

A typical dice has 6 sides, 3 (50%) even and 3 (50%) odd. Therefore 50% of rolls should theoretically result in an even number. 50% of 132 is the same as *132, which can be written as . This can be evaluated to 66. This is not necessarily the amount of times it will occur (as there are discrepancies), but it is the approximate amount expected of a dice with an even amount of sides.

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
