Answer:
B. 10/91
Step-by-step explanation:
Box has 5 red buttons and 9 blue buttons.
We add 5 and 9 to get the total buttons. 
5 + 9 = 14 
Then, we find the probability for a red button. 
5/14 = .35 
Now, that we've taken out 1 button. 
The amount of buttons available changes. 
14 - 1 = 13 
There are 4 red buttons remaining. 
The probability for a red button changes to 4/13. 
4/13 = .30 
Then, we multiply both probabilities. 
.30 x .35 = .111
Convert to a fraction. 
.111 = 10/91 
Thus it would be B.
