The Mars Candy Company has announced on its website that 20% of its Peanut M&M's are red and 80% are of different colors. We randomly select a Peanut M&M packet. We found that it has 100 pieces. What is the probability that 24% or more of the M&M's in that packet are red? (Use the empirical rule if needed.)

Can you please show me the formula I would need to enter in EXCEL (eg. Norm.dist) to solve this problem, thank you!

A) 50%

B) 2.5%

C) 84%

D) 16%

E) 97.5%
