Question

When your flip a biased coin the probability of getting a tail is 0.75. How many times would you expect to get tails if you flip the coin 160 times?

Answer 1

expected number outcomes=probability outcome time the number of trials.

n=(3/4)t, we are told that their will be 160 trials so:

n=(3/4)160

n=120

So you would expect to flip tails 120 times in 160 flips.
