Answer 2

Answer:

3/5

Step-by-step explanation:

10 possible committees: (A, B, C), (A, B, D), (A, B, E), (A, C, D), (A, C, E), (A, D, E), (B, C, D), (B, C, E), (B, D, E) and (C, D, E)

Of these, Burke is included in 6: (A, B, C), (A, B, D), (A, B, E), (B, C, D), (B, C, E) and (B, D, E)

So:

The Number of ways it can happen = 6

The Total number of outcomes = 10

6/10 = 3/5
