Answer:
7/9
Step-by-step explanation:
P(blue) = 2:7
This means there are 2 blue parts for every 7 nonblue parts. So 9 parts total! 2:7, then, should be thought of as 2/9.
P(not blue) = 1 - 2/9
= 7/9
Think about it: there must be a total probability of 1, so the probability of <em>not</em> getting blue must be 7/9.
