Answer 1

The probability that a 4 shows up is 0.20 and the proportion of 3's rolled is 0.467

The probability that a 4 shows up

From the list of numbers, we have:

• Sides = 5 i.e. numbers 1 to 5
• n(4) = 1 i.e. sides labelled 4

The probability that a 4 shows up is then calculated as:

P = n(4)/Sides

This gives

P = 1/5

Evaluate

P = 0.2

The proportion of 3's rolled

In the list of numbers, we have:

• Total = 15
• Number of 3's = 7

The proportion of 3's rolled is then calculated as:

P = Number of 3's/Total

This gives

P = 7/15

Evaluate

P = 0.467

Hence, the proportion of 3's rolled is 0.467
