You roll a number cube. Find the probability and write your answer in the simplest form. P(4)= P(not a 2) = P(3 or 5) =

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Number cube:

A number cube is a dice, which has six sides, numbered 1 to 6.

P(4)

One the sides is a 4, thus:

P(not a 2)

Of the 6 sides, one is a 2, and the other 5 are not 2. So

P(3 or 5)

One sides is 3, other is 5, 1 + 1 = 2. So

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
