Correct answer is B
Let the number of students that like both Science and History = x
Number of Science only = 35 - x
Number of History only = 30 - x
35 - x + 30 - x + x = 50
65 - x = 50
x = 15
P(Science and History) = \(\frac{15}{50} = 0.30\)

Correct answer is A
Differentiate distance twice to get the acceleration and then equate to get p.
\(s = 7 + pt^{3} + t^{2}\)
\(\frac{\mathrm d s}{\mathrm d t} = v(t) = 3pt^{2} + 2t\)
\(\frac{\mathrm d v}{\mathrm d t} = a(t) = 6pt + 2\)
\(a(3) = 6p(3) + 2 = 8 \implies 18p = 8 - 2 = 6\)
\(p = \frac{6}{18} = \frac{1}{3}\)
