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?

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.
