For a binomial distribution, which probability is not equal to the probability of 1 success in 7 trials where the probability of success is 0.277?
Select one:
a) Probability of 6.000 failures in 7 trials where the probability of success is 0.723
b) Probability of 1 success in 7 trials where the probability of failure is 0.723
c) Probability of 6.000 failures in 7 trials where the probability of failure is 0.723
d) Probability of 6.000 failures in 7 trials where the probability of success is 0.277

Step 1
Probability of 6.000 failures in 7 trials where the probability of success is 0.723
because,
$\text{probability of success}=0.277\phantom{\rule{0ex}{0ex}}\text{Hence probability of failure}=1-\text{probability of success}\phantom{\rule{0ex}{0ex}}\text{probability of failure}=1-0.277\phantom{\rule{0ex}{0ex}}\text{probability of failur}=0.723$
in first option probability of success is 0.723 given
hence first option is incorrect.
