There are 12 counters in a bag.
3 of the counters are red.
1 of the counters is blue.
2 of the counters are yellow.
the rest of the counters are green.
caitlin takes at random a counter from the bag.
(c) show that the probability that this counter is yellow or green is
in

the probability is 8/12 or 67%

Step-by-step explanation:

two yellow counters and 6 green counters make up 8 of the 12 counters for the fraction of 8/12. 8 is 67% of 12.

idk if you do percentage or not but I did it anyway.

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
