Question

Predict how many times you will roll a number less than 3 if you roll a standard number

cube 350 times. Round to the nearest integer, if necessary.

You will roll a number less than 3 about

times.

Answer 1

about 117 times

Explanation:

No. of possible outcomes of a cube: 6

2 out the 6 possible outcomes are less than 3,

and therefore, No. of favorable outcome: 2

P(less than 3)= No. of favorable outcome / No. of possible outcomes

=2/6 => 1/3

if you roll a standard number cube 350 times then,

Prediction= number of rolls x (P(less than 3))

=350 x 1/3

≈117 times.
