mojhsa [17]

Answer:

1. Option A

2. 56

Explanation:

1.

Option A

Option A is not a valid answer for this question as it is given that out of eight rats only two rats are untrained. Thus, an output which shows more that two untrained rats i.s UUTTU is a wrong answer

2.

8C_5 = \frac{8!}{5!(8-5)!} \\8C_5 = \frac{8*7*6*5!}{5! * 3!} \\8C_5 = \frac{8*7*6}{3*2*1} \\8C_5 = 56

Thus , there are 56 outcomes possible for this experiment
