Ответ:
7/9
Step-by-step explanation:
Given:
Number of yellow cards=2
Number of red cards=12
Number of blue cards=4
Total number of cards= Number of yellow cards+Number of red cards+Number of blue cards
= 2+4+12=18cards
Probability of a NON-blue card = number of non blue/ total number
where NON-blue= Number of red cards+
Number of yellow cards
= 2+12=14
P(not blue)=
=14/18
7/9
Therefore, probability that the card is not blue is 7/9
