There are 6 total possibilities when rolling the die  1,2,3,4,5,6

P (green or even) = green or even/ total

eimsori [14]

Answer:

  • 5/12

<em>Probability = favorable outcomes / total outcomes</em>

  • P(odd) = 3/6 = 1/2    (there are 3 odd numbers out of 6 on a dice)
  • P(no 1) = 5/6
  • P(odd and no 1) = 1/2*5/6 = 5/12
