Question 1200285
<font color=black size=3>
Answers:
(a) <font color=red size=4>0.88</font>
(b) <font color=red size=4>0.27</font>
(c) <font color=red size=4>0.003</font>
(d) <font color=red size=4>0.377</font>
(e) <font color=red size=4>0.623</font>


Explanation:


(a) 12% are brown, so 100%-12% = 88% are not brown. 
This percentage converts to <font color=red>0.88</font>


(b) 15% are yellow and 12% are red. 
That's a total of 15+12 = 27% which converts to <font color=red>0.27</font>


(c) 15% are green which converts to 0.15
Getting 3 green in a row has probability (0.15)^3 = 0.003375 = <font color=red>0.003</font> when rounding to three decimal places.


(d) 15% are yellow, so 85% are not yellow. 
Getting 6 non-yellow candies in a row has probability (0.85)^6 = 0.377149515625 which rounds to <font color=red>0.377</font>


(e) Subtract the previous result from 1 to get 1-0.377 = <font color=red>0.623</font>
This works because P(at least one yellow)+P(none are yellow) = 1
The events are complementary.
