Approximating a binomial distribution - Correct Answer ✅💯If n
is large and p is close to 0.5 the binomial can be approximated
as a normal dist where the mean=(numberxprobability)
standard dev=root(numberxprob)x(1-p)
you need to apply a continuity correction
Area in a velocity-time graph - Correct Answer ✅💯Distance
travelled
Average speed - Correct Answer ✅💯=total distance
travelled/time taken
Average velocity - Correct Answer ✅💯=total
displacement/time taken
Binomial distribution - Correct Answer ✅💯X~B(n, p) where n is
a fixed no. of trials, p is the probability of success and there are
only 2 outcomes, success and failure, the trials are independent
