7.10 Exercise 5

Avg difficulty 2.5

Suppose we are about to flip a fair coin 50 times. Let HH represent the number of heads that result from those flips. Use technology to find the following:

  1. P(H≤22)P \left(H \leq 22\right)
  2. P(H<26)P \left(H < 26\right)
  3. P(H>28)P \left(H > 28\right)
  4. P(H≥20)P \left(H \geq 20\right)
  5. P(20<H<25)P \left(20 < H < 25\right)
