If a standard dice ius rolled 50 times what s the theretical probibility of rolling a 4
saul85 [17]

We seems to be being asked the probability of rolling at least one four in fifty tries, which should be pretty high. As usual with "at least" questions, we write

p = P(at least one 4) = 1 - P(no fours at all)

The probability of a four on one roll is of course 1/6, so the probability for "not a four" is 1-1/6=5/6. We want the probability of a conjunction of 50 independent events: no four on the first roll and no four on the second roll and...

For a conjunction of independent events we multiply their probabilities. That's 5/6 times itself 50 times. So our answer is

p = 1 - \left( \frac 5 6 \right)^{50}

If we need a decimal approximation, it's

p \approx 0.999890 = 99.9890\%

Solve the radical equation q-6=√27-2q
rewona [7]

q - 6 = sqrt(27 - 2q)

Squaring both sides:-

(q - 6)^2 = 27 - 2q

q^2 - 12q + 36 = 27 - 2q

q^2 - 10q + 9 = 0

(q - 9)(q - 1) = 0


so there are 2 solutions q = 1 and q = 9.


Testing to see if the solutions are not extraneous:-


q = 9:-

9 - 6 = 3

sqrt(27-18) = 3 So q = 9 is a solution (answer)


q = 1

q - 6 = -5

sqrt (27 - 2) = sqrt 25 = -5 so q = 1 is also an answer
