The probability of an event P(n), is equal to the number of the outcomes of that event n(E), divided by the total number of outcomes, or the sample space, n(S)
so
The probability of an event = 1 - probability of the same event not to happen
so P(not need repair within the first year)=1-0.25=0.75
Answer: a) 0,25; b) 0,75
Here's one way to convert the number to the ratio of integers.
- Count the number of repeating digits. Call this number <em>n</em>. Here, only 5 has an overline, so there is only one repeating digit. That is, <em>n </em>= 1.
- Multiply the number by 10^(-n) and subtract that from the original number. Call the result <em>p</em>. Here, doing this gives
- Compute the value <em>q</em> = 1 - 10^(-n). The result of step 2 is <em>q</em> times the original number. Here, <em>q</em> = 1 - 10^-1 = 0.9.
- Create the fraction <em>p/q</em>. Note that both <em>p</em> and <em>q</em> have a finite number of decimal digits, so this is easily converted to the ratio of integers, by moving the decimal point an equal number of places in the numerator and denominator. Reduce the resulting fraction as may be required. This is the fraction you're looking for. Here, p/q = 3.23/0.9 = 323/90. No reduction of this fraction is possible.
The fraction you're looking for is ...

<span>We can rewrite the fraction in different ways.
For this, what we must do is multiply the numerator and the denominator by the same number and simplify.
We have then:
