Answer:
C. 2/3
Step-by-step explanation:
p(event) = (number of desired outcomes)/(total number of outcomes)
The total number of outcomes is the sum of the numbers of all chips.
5 + 3 + 7 = 15
The desired outcomes are any red or blue chips to be drawn.
There are 3 red chips and 7 blue chips.
3 + 7 = 10
Number of desired outcomes = 10
p(red or blue) = 10/15 = 2/3
