Using the principle of binomial probability, the probability that more than 3 friends win a prize is
Recall :
- P(x = x) = nCx * p^x * q^(n-x)
<u>Given</u><u> </u><u>the</u><u> </u><u>Parameters</u><u> </u><u>:</u>
- <em>Probability</em><em> </em><em>of</em><em> </em><em>success</em><em>,</em><em> </em><em>p</em><em> </em><em>=</em><em> </em><em>1</em><em>/</em><em>6</em><em> </em>
- <em>q</em><em> </em><em>=</em><em> </em><em>1</em><em> </em><em>-</em><em> </em><em>p</em><em> </em><em>=</em><em> </em><em>5</em><em>/</em><em>6</em><em> </em>
- <em>Number</em><em> </em><em>of</em><em> </em><em>trials</em><em>,</em><em> </em><em>n</em><em> </em><em>=</em><em> </em><em>7</em>
- <em>x</em><em>≥</em><em>3</em><em> </em>
Hence,
P(x ≥ 3) = p(x = 3) + p(x = 4) + p(x = 5) + p(x = 6) + p(x = 7)
P(x ≥ 3) = 0.0781 + 0.0156 + 0.0019 + 0.0001 + 0.000003
P(x ≥ 3) = 0.095703
Therefore, the probability that more than 3 friends win a prize is 0.0957

Your life purpose consists of the central motivating aims of your life—the reasons you get up in the morning. Purpose can guide life decisions, influence behavior, shape goals, offer a sense of direction, and create meaning. For some people, purpose is connected to vocation—meaningful, satisfying work.
