Number 1 2 3 4 5 6
Frequency 18 22 20 16 10 14

The table represents the outcome of throwing a die 100 times. What is the probability of obtaining at least a 4?

Worked solution (try it first)
  1. The die was thrown 100 times.
  2. At least 4 means 4, 5 or 6: 16+10+14=4016 + 10 + 14 = 40 throws.
  3. So the probability is 40100=25\frac{40}{100} = \frac25, option D.
