\text{P(Marvin wins}) = 30\%P(Marvin wins)=30%start text, P, left parenthesis, M, a, r, v, i, n, space, w, i, n, s, end text, right parenthesis, equals, 30, percent
\text{P(Aly wins}) = 0.2P(Aly wins)=0.2start text, P, left parenthesis, A, l, y, space, w, i, n, s, end text, right parenthesis, equals, 0, point, 2
\text{P(Hank wins}) = \dfrac12P(Hank wins)=
