Answer:
As there is Bracket lats solve it first but as there is '-' sign before the bracket sign in the bracket will change. so we will have,
'800+900×25-65(89-5)-12÷67-7'
Solving the bracket gives us:
'800+900×25-65(84)-12÷67-7'
Now avoiding the Bracket:
'800+900×25-5460-12÷67-7'
Now first we have to do MUltiplication, so we will get,
'800+22500-5460-12÷67-7'
Now let's do the division, so we will get,
'800+22500-5460-0.17-7'
Now lets do the additions and subtractions we will get,
<h2><u>17,832.83</u></h2>

Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:

In which
is the decay parameter.
The probability that x is lower or equal to a is given by:

Which has the following solution:

The probability of finding a value higher than x is:

Mean of 10 minutes:
This means that
