Q. Work out the chance of making these scores with a die.
(a) The probability of rolling a 'six'?
(b) The probability of rolling a 'one' ?
(c) The probability of rolling a 'six' or a 'one' ?
(d) The probability of rolling a 'one', 'six', or 'three'?
(e) The probability of rolling a 'two', 'six', 'five', or 'three' ?
Hi,
With a die we can score from 1 to 6 score.
a. The probability of rolling a 'six= 1/ 6
(b) The probability of rolling a 'one' = 1/6
(c) The probability of rolling a 'six' or a 'one' = 1/6+1/6 = 1/3
(d) The probability of rolling a 'one', 'six', or 'three'= 1/6+1/6+1/6 = 1/2
(e) The probability of rolling a 'two', 'six', 'five', or 'three' =1/6+1/6+1/6+1/6 = 2/3
