Committee of 7 students is to be formed from 10 ee students, 12 cs students and 8 math students. it is required that at least two students from each major be on the committee. if all possible committees are equally likely, find the probability of forming a committee with 3 ee students.

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
