What is the probability that the group attending will have at least 3 students? There are 4 girls and 2 boys in an art class. Four will be chosen at random to act as greeters for the school’s art exhibit. What is the probability that at least three girls will be chosen? The probability of randomly picking 5 puppies of which at least 3 are male, from group of 5 males and 4 females? The probability that a group of 6 people selected from 7 men and 7 women will have at least 3 women?

2. … Combinations There are 5 students and 4 teachers on the school newspaper committee. A group of 5 members is being selected at random to attend a workshop. What is the probability that the group attending will have at least 3 students? P(≥3 students) = P(3s & 2t) + P(4s & 1t) + P(5 s & 0t)

3. … Combinations There are 4 girls and 2 boys in an art class. Four will be chosen at random to act as greeters for the school’s art exhibit. What is the probability that at least three girls will be chosen? P(≥3 girls) = P(3g & 1b) + P(4g & 0b)

4. … Combinations The probability of randomly picking 5 puppies of which at least 3 are male, from group of 5 males and 4 females? The probability that a group of 6 people selected from 7 men and 7 women will have at least 3 women?
