Answer:
Step-by-step explanation:
We require more information by I will explain in principle:
If Type A has at least 300 hours and Type B at least 400 hours.
You need to determine the Probability density function of X and Y and then subtract 1 from both
This will give you the probability of the expression.
Use the way that kids use i.e trial and error method .
Solution:-
The set given by
Lets understand
Come to 2nd one.
Come to third one
Lets think
Nearest squares to 225 are 196 and 289
We can't take 196 as we have to take a positive one other wise it will come in terms of i.
Take 289
Its divisible by 8 .
Rewrite the set
Hence n=64
