You said the answer in your question??
We need to define the variables,
So,

Therefore, the probability that the repair time is more than 4 horus can be calculate as,

The probability that the repair time is more than 4 hours is 0.136
b) The probability that repair time is at least 12 hours given that the repair time is more than 7 hoirs is calculated as,


The probability that repair time is at least 12 hours given that the repair time is more than 7 hours is 0.63

umm , is it okay if we do this on microsoft word , cuz i cant send pics of answers here...
Answer:
Explanation:
var generator = new Random(1);
// Now the nextGaussian() function returns a normal distribution of random numbers with the following parameters: a mean of zero and a standard deviation of one
var draw = function() {
var num = generator.nextGaussian();
var standardDeviation = 60;
var mean = 2003;
// Multiply by the standard deviation and add the mean.
var x = standardDeviation * num + mean;
noStroke();
fill(214, 159, 214, 10);
ellipse(x, 200, 16, 16); };
Hope this will be helpful
