If one out of the last nine customers wanted mustard on their hotdogs what is the experimental probability that the next customer that comes in will want mustard on their hotdogs.

1/10?

no 9/10

how about 1/9 ?

If one out of the first nine wants one then the probability that a customer wants one is 1/9

To calculate the experimental probability that the next customer will want mustard on their hotdogs, you need to analyze the given data. In this case, you know that out of the last nine customers, one wanted mustard on their hotdogs. The experimental probability can be calculated by dividing the number of favorable outcomes (customers who wanted mustard) by the total number of outcomes.

In this case, the number of favorable outcomes is one (one customer wanted mustard), and the total number of outcomes is nine (nine customers in total).

To calculate the experimental probability, divide the number of favorable outcomes by the total number of outcomes:

Experimental Probability = Number of Favorable Outcomes / Total Number of Outcomes
= 1 / 9

Therefore, the experimental probability that the next customer will want mustard on their hotdogs is 1/9.
