Answer: B
Work:
-5x+10>-15 = x<3/10
So, you should add the heighth twice and add the width twice too, then add those two together to get your answer.
The value of the probability P(S or T) is 39%
<h3>How to determine the probability?</h3>
The probability values are given as:
P(S) = 12% P(T) =27%
For mutually exclusive events,
P(S or T) = P(S) + P(T)
This gives
P(S or T) = 12% + 27%
Evaluate the sum
P(S or T) = 39%
Hence, the value of the probability P(S or T) is 39%
