Probability: If you roll a regular 6-faced die 1200 times, about how many times would you expect to get a 4?

just olya [345]

If you roll a six sided dice once, each outcome has a 1/6 probability.

This means 4 has a 1/6 probability.

If you roll a dice 1200 times....

1200 × 1/6 = 1200/6 = 200

You would expect to get a 4 200 times.

For this case we have that by definition of power properties it is fulfilled that:

$(a ^ n) ^ m = a ^ {n * m}$

We must rewrite the following function:

$f (x) = 7 (\frac {1} {2})^{3x}}$

Using the mentioned property we have:

$f (x) = 7 ((\frac {1} {2}) ^ 3) ^ x$

Solving the operation within the parenthesis we have:

$f (x) = 7 (\frac {1 ^ 3} {2 ^ 3}) ^{ x}\\f (x) = 7 (\frac {1} {8})^{x}$

Thus, the correct option is option B
