The fractional part of the first number is too small so let's borrow one from it:

8 and 4/6 can be written as 7 and 6/6 and 4/6.

I took a full unit from the 8 and wrote it in terms of sixths.
Now combine the fractional parts,

7 and 10/6,
and we're taking away 2 and 5/6 from this amount.

7 - 2 = 5

10/6 - 5/6 = 5/6

giving us 5 and 5/6 as a result.

Understand? :)

You have to do 4/6-5/6 first but u have to regroup I think. Which means it would be 10/6-5/6. The answer would be 5/6. Then subtract 7-2 and u get 5. Which means the answer is 5 and 5/6

What is the reliability of a two-component product if the components are in parallel, with individual reliabilities of 0.95, and
user100 [1]

The reliability of a two-component product if the components are in parallel is 0.99.

In this question,

The probability of failure-free operation of a system with several parallel elements is always higher than that of the best element in the system. Reliability can be increased if the same function is done by two or more elements arranged in parallel.

A system contains two components that are arranged in parallel, they are 0.95 and 0.80.

Therefore the system reliability can be calculated as follows

⇒ 1 - ( 1 - 0.95 ) × ( 1 - 0.80 )

⇒ 1 - (0.05 × 0.20)

⇒ 1 - 0.01

⇒ 0.99

Hence we can conclude that the reliability of a two-component product if the components are in parallel is 0.99.
