Answer:
E(Bases ) = 0.6584499955929 choice C.
Step-by-step explanation:
We want Expected number of bases during 2009
E(bases) = SUM (number of outcomes) *probabiility of outcome
93 + 45 + 1 + 47 = 176 hits
but there are a total of 568 bats
568 - 176 = 392 misses?
E(Bases) = 0* P( miss) + 1 * P( hitting singles) + 2*P(hitting doubles) + 3*P(hitting triples) + 4*P(home run)
E(Bases) = 0 + 93/568 + 2* (45/568) + 3*(1/568) + 4*(47/568)
0.16373239 + 0.158450 + 0.0052816901 + 0.33098591549
E(Bases ) = 0.6584499955929
