9C5 ways to choose the groups=126 ways
-
ii. numerator its 5C3*4C2 for 3 women and therefore 2 men=60, so there are 60 ways
-
iii probability is 60/126 or 10/21.
-
iv. at least 3 women includes 3,4,5. We know 60 ways for 3. For 4 it is 5C4*4C1=20 ways and for 5 women there is only one way. Therefore , there is 81/126 probability or 9/14.
v.Look at 2 women this has 5C2*4C3=40 ways
For 1 woman 4C4*5C1=5 ways.
Can't be 0 women.
1woman-4 men=5 ways
2W 3M-40 ways
3W2M-60 ways
4W1M-20 ways
5W0M-1 way
They add up to 126. They have to.
More men then women occurs 4/1 (5 ways) 3/2 (40 ways) no other ways. so probability is 45/126=15/34
