Let's denote students in D = in the drama club , S<span> = in a sports team </span> <span>P(D) = 85/330 </span> <span>P(S) = 200/330 </span> <span> P(D and S) = 60/300 </span> <span> P(D or S) = P(D) + P(S) - P(D and S) </span><span>= 85/330 + 200/330 - 60/330 = 15/22 </span> <span> P(neither D nor S) = 1- 15/22 </span><span>= 7/22</span>
This is an example of a distribution property. In a
distribution property, the number outside the parenthesis is distributed to all
the terms inside it by multiplication. So the answer here is:
<span>The 4 will be multiplied to each term inside the
parentheses.
