The probability that the card is not yellow is
<em><u>Solution:</u></em>
<em><u>The probability of an event is given as:</u></em>
From given,
A box is filled with 8 blue cards, 8 yellow cards, and 2 green cards
Total number of possible outcomes = 8 + 8 + 2 = 18
Favorable outcome = card is not yellow
Favorable outcome = card is blue or green = 8 + 2 = 10
Therefore,
Thus the probability that the card is not yellow is 5/9
