Answer:
A) randomNumber = 0.70;
Step-by-step explanation:
The code works perfectly for all values of randomNumber given in the options except option (a)
This is so because:
The first condition
if (randomNumber <= 0.70) { event = 1; }
It checks if randomNumber is less than or equal to 0.70. This is true, so event is set to 1.
However, the next condition after it will also be executed because it is a different conditional to be executed.
So, we have:
if (randomNumber <= 0.80) { event = 2; }
This condition is also true, so event is set to 2.
From the question randomNumber is meant to be event 1. However, this is different from the result of executing the code.
Hence, (a) is true
