On December 15, 2000, 10 M&Ms were weighed on a scale in a Chemistry Lab. The average weight obtained was 2.2194 grams. Suppose the probability is 70% that the M&Ms weigh more than 2 grams. Let X be the the number of M&Ms that weigh more than 2 grams in a sample of 10 M&Ms. Find
1. P (X = 10)
2. P (X <= 7)
3. P (X >= 7)
