Answer:
3/25
Step-by-step explanation:
Since it is stated that 12/25÷4
It can also be written as 12/25/4
Which means 12/25×1/4
So let's solve
3/25
The Reason why we get 3/25 is because 12 is being divided by 4
So the final answer to the given question is 3/25
He bought 3 cucumbers because 3*5=15, 15-6=9, 9*.7=6.3, .3*3=.9, .9+6.3=7.2
Answer:
−4+5−2
Step-by-step explanation:
Just combine the like terms which are 3y and 2y, you add and get 5y and everything else stays the same
The probability any one system works is 0.99
So the probability of any one system failing is 1-0.99 = 0.01, so basically a 1% chance of failure for any one system
Multiply out the value 0.01 with itself four times
0.01*0.01*0.01*0.01 = 0.000 000 01
I'm using spaces to make the number more readable
So the probability of all four systems failing is 0.00000001
Subtract this value from 1 to get
1 - 0.00000001 = 0.99999999
The answer is 0.99999999 which is what we'd expect. The probability of at least one of the systems working is very very close to 1 (aka 100%)
