The probability that an individual will score of 50 or less is 0.06.

Given mean of 60 and standard deviation of 8.

We have to find the probability that individual will score 50or less.

Probability is the chance of happening an event among all the events possible. The probability lies between 0 and 1. The formula to calculate probability is as under:

Probability = number of items/total items.

We have to first find the z value from 50 to 60 which can be found as under:

z value=(50-60)/60

=-0.167

P value from 50 to 60 is 0.44

probability that the individual will score 50 or less is 0.5-0.44

=0.06

Hence the probability that the individual will score 50 or less is 0.06.

The sum of two numbers is 60 and the difference is 2 what are the numbers.
oksian1 [2.3K]
Let the two numbers be x and y
Then
x + y = 60
And
x - y = 2
x = y + 2
Putting the value of x in the first equation we get
x + y = 60
y + 2 + y= 60
2y + 2 = 60
2y = 60 - 2
2y = 58
y = 58/2
y = 29
Now putting the value of y in the first equation we get
x + y = 60
x + 29 = 60
x = 60 - 29
x = 31
So the value of the two numbers comes out to be 31 and 29. I hope the procedure is clear enough for you to understand.
