Find the probability of atleast three successes in six trials of a binomial experiment in which the probability of success is 50%.

The binomial cumulative probability with p=0.5 for 3+ successes is as follows:

for p=0.5 (50% success rate) it becomes:

the probability is 0.65625, or about 66%

1760 kilometers

step-by-step explanation:

multiply the amount of time the plane took to travel by it's speed

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
