There are 6 numbers on a die : 1, 2, 3 , 4, 5 , 6
numbers greater than 3 are 4, 5 and 6
number less than 2 is 1
There are 4 possible outcomes from 6, hence
Probability = [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{3}[/tex]
The probability of rolling a number greater than 3 or less than 2 is 2/3
- Probability is the likelihood or chance that an event will occur.
- Probability = Expected outcome/Total outcome
- If a single die is rolled once, the total outcome will be n(S) = 6
If a number greater than 3 is rolled, event putcome will be E = {4, 5, 6}
- n(E) = 3
Pr(greater than 3) = 3/6
If a number less than 2 is rolled, event outcome will be E = {1}
- Pr(less than 2) = 1/6
Pr( number greater than 3 or less than 2) = 3/6 + 1/6 = 4/6
