Question

When you flip a biased coin the probability of getting a tail is 0.4.

How many times would you expect to get tails if you flip the coin 160 times

Answer 1

64 times

Explanation:

Multiply 0.4, the chance of getting tails, which 160, the amount of times you flip the coin, and you get 64. This is reasonable, because the probability of getting heads is 0.6, and if you flip the coin 160 times, you will get heads 96 times. Hope this helped :)
