Answer:
- Total number = 30
- Number of females = 12
- Number of males = 18
a) <u>Combination of 5 out of 30:</u>
- 30C5 = 30!/[5!*(30 - 5)!] = 142506
b) <u>Combination of 2 males:</u>
- 18C2 = 18!/[2!*(18 - 2)!] = 153
<u>Combination of 3 females:</u>
- 12C3 = 12!/[3!*(12 - 3)!] = 220
<u>The number of ways with 2 males and 3 females:</u>
c) <u>Required probability is:</u>
- P(2 males and 3 females) = 33660 / 142506 = 0.236
