Answer:
Probability = 0.12676992
Step-by-step explanation:
The probability of selecting committee of seven composed of all Democrats.
Total number = 45+55= 100
Number of Democrats = 55
Number of committee = 7
Probability= (55C7)/(100/7)
Where C represent combination sign
Probability = (202927725/1.60075608*10^10)
Probability = 0.12676992
