probability of coin2 heads up: [tex] \frac{1}{2} [/tex]
probability of coin3 tails up: [tex] \frac{1}{2} [/tex]
probability of coin1 heads, coin2 heads, and coin3 tails: [tex] \frac{1}{2} [/tex]× [tex] \frac{1}{2} [/tex]× [tex] \frac{1}{2} [/tex]
=[tex] \frac{1}{8} [/tex]
convert to a percent if needed.
