Answer: 0.5
Step-by-step explanation:
Formula for binomial probability :-
, where P(x) is the probability of getting success in x trials , n is the total number of trials and p is the probability of getting success in each trial.
Given : The number of trails : n=7
The probability of success for each trial : p=0.5
Now, the probability that the number x of correct answers is fewer than 4 will be :-

Hence, the probability that the number x of correct answers is fewer than 4 = 0.5
480
This is this awnser because its 120 a second, for 4 seconds so 4 times 120 = 480.
Answer:
I pretty sure it's C or lllll
