\frac{(x+1)(x-1)}{(x+1)(x-1)(x+1)} - \frac{2(x-1)}{(x+1)(x-1)(x+1)} +  \frac{3(x+1)}{(x+1)(x-1)(x+1)}

=\frac{x^2-2-2x+2+3x+3}{(x+1)(x-1)(x+1)}
= \frac{x^2+x+4}{(x+1)(x-1)(x+1)} is what I got.

If an event has a 55% chance of happening in one trial, how do I determine the chances of it happening more than once in 4 trial
aev [14]

The chances of it happening more than once in 4 trials is 13%

<h3>How to determine the number</h3>

From the information given, we have can deduce that;

Probability of 1 trial = 55%

= 55/ 100

Find the ratio

= 0. 55

We are to find the probability of it happening more than once in 4 different trials

If the probability of it happening in one trial is 555 which equals 0. 55

Then the probability of it happening in 1 in 4 trials is given as;

P(1/4 trials) = 1/ 4 × 55%

P(1/4 trials) = 1/ 4 × 0. 55

Put in decimal form

P(1/4 trials) = 0. 25 × 0. 55

P(1/4 trials) = 0. 138

But we have to know the percentage

= 0. 138 × 100

Multiply the values, we have

= 13. 8 %

Thus, the chances of it happening more than once in 4 trials is 13%
