The probability of a given event is . if the experiment is repeated n times, what is the probability that the event does not occur in any of the trials?
ill give u brainliest and 30 points

Events with two possible outcomes are modelled by the following equation: if the probability of success is , you have trials, and X is the random variable representing the number of times the event with probability p happens, you have

Now, you want X=0 (i.e. the event never happens). So, you have

it should be a and d. lmk if i'm wrong xd

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
