Answer 1

Answer:

The two experiments together can be performed in 45 distinct ways.

Step-by-step explanation:

Number of distinct ways to perform first experiment = 5

Number of distinct ways to perform first experiment = 9

For each distinct way the first experiment is performed there are 9 distinct ways to perform the second experiment. Also, the way each experiment is performed is independent of the other experiment (important assumption).

So, according to the fundamental rule of counting the total number of ways to perform both the experiments must be equal to the product of number of ways in which each experiment can be performed.

Therefore, the two experiments can be performed together in 5 x 9 = 45 distinct ways.
