Answer
a) 0.000969
b)$7.15⋅10^{−8}$
c) 0.436
Work Step by Step
By the given formula:
a)$P=\frac{{6 \choose 4} \cdot {43 \choose 2}}{{49 \choose 6}}=0.000969$
b)$P=\frac{{6 \choose 6} \cdot {43 \choose 0}}{{49 \choose 6}}=7.15 \cdot 10^{-8}$
c)$P=\frac{{6 \choose 0} \cdot {43 \choose 6}}{{49 \choose 6}}=0.436$
