(2 x 103 x 3 x 105) = 64890
2 x 10 -2 = 20 - 2 = 18
64890 / 18
3605
Or (206 x 315) / 20 - 2
Answer:
A. 5
Step-by-step explanation:
12 times 5 is 60 plus 10 is 70. 70 < 75
Answer:
<em>(C). {3} </em>
Step-by-step explanation:
= 
+ 
( x ≠ - 1 )
- + = 0
- 
= 0
= 0 ⇒ <em>x = 3</em>
Answer:
P ( X > 5 ) = 72,2 %
Step-by-step explanation:
The probability of success ( outcomes bigger than 5 )
If dice 1 outcome is 6 no matter wich outcome we get from dice 2 all events are successful, the we have 6 outcomes
If dice 1 outcome is 5 we also have 6 outcomes
If dice 1 outcomes is 4 we have 5 positive outcomes
If dice 1 outcome is 3 we have 4 positive outcomes
If dice 1 outcome is 2 we have 3 positive outcomes
if dice 1 outcome is 1 we have 2 positive outcomes
Total evaluating dice 1: positive outcomes 26
We will get the sames results analysing dice 2 then we have a total of
52 successful events
And total numbers of outcomes is 36 + 36 = 72
Then
P ( X > 5 ) = 52/72
P ( X > 5 ) = 0,722
P ( X > 5 ) = 72,2 %
