After subtracting 3 from 7, and dividing 4 by 2, you should end up with x=2.
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
283.5
So you multiply 6.75 by 21 stools to find the total number of meters. Then you multiply that by 2.
The answer is 1432 x 54 = 77,328
