Question 17 of 90 in this shift, Maths question 17 of 30, Section A.

Let E1\mathrm{E}_1, E2\mathrm{E}_2, E3\mathrm{E}_3 be three mutually exclusive events such that P(E1)=2+3p6\mathrm{P}(\mathrm{E}_1) = \frac{2 + 3\mathrm{p}}{6}, P(E2)=2−p8\mathrm{P}(\mathrm{E}_2) = \frac{2 - \mathrm{p}}{8} and P(E3)=1−p2\mathrm{P}(\mathrm{E}_3) = \frac{1 - \mathrm{p}}{2}. If the maximum and minimum values of p are p1\mathrm{p}_1 and p2\mathrm{p}_2, then (p1+p2)(\mathrm{p}_1 + \mathrm{p}_2) is equal to :
