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%
