During his 2007 MVP season for the New York Yankees,
who cares

Alex Rodriguez hit
98 singles, # column 1
31 doubles, # column 2
0 triples, and # column 3
54 home runs in a # column 4
583 total of bats.

The following table arranges these data in terms of the

number of bases for a hit, counting 0 bases for the times when he did not get a hit and
4 bases for home runs.

Number of Bases 0 1 2 3 4
Number of Times 400 98 31 0 54

# So they gave the info twice

To the nearest thousandth,
? E(X), the expected number of bases for Alex Rodriguez in a typical at bat in 2007?

a run is taken as 4 bases

I think that:
the expected nr of bases is the average number of bases at bat
that is
E(X) = Total bases / total of bats

Given is
Total of bats = 583

the total nr of bases =
1*singles + 2*doubles + 3*triples + 4*home-runs =
1*98 + 2*31 + 3*0 + 4*54 =
98 + 62 + 0 + 216 = 160 + 216 = 376

So,
the expected number of bases for Alex Rodriguez in a typical at bat in 2007,
E(x) = 376 / 583 = 0.644939966
Hence
To the nearest thousand:

The expected number of bases for Alex Rodriguez in a typical at bat in 2007,
E(x) = 376 / 583 = 0.644939966

Hence
To the nearest thousand:

The expected number of bases for Alex Rodriguez in a typical at bat in 2007,
E(x) = 376 / 583 = 0.645
