Question

A number cube with the numbers 1, 2, 3, 4, 5, and 6 is rolled 1000 times. About how many times would it be expected that a number greater than 4 is rolled?

A.
667

B.
167

C.
500

D.
333

Answer 1

there are two (5 and 6) numbers that are greater than 4.
that is 2 out of six, so the percentage is
\[\frac{2}{6}=\frac{1}{3}\]which is about 0.333 (33.33%).
33.33% of 1000 is \[1000(0.333)=333\]

Answer 2

2/6 = x/1000
x=333
