To calculate the probability of a random selection falling between -1.2 and 1.3 knots, we need some additional information. Specifically, we need to know the range of values from which the selection is made.
Assuming we have this information, we can use the following formula to calculate probability:
Probability = (Number of favorable outcomes) / (Total number of possible outcomes)
In this case, the favorable outcomes are the values that fall between -1.2 and 1.3 knots. The total number of possible outcomes is the total range of values from which the selection is made.
To find the probability, you need to know the specific range from which the selection is made. Once you have that information, you can plug it into the formula above to calculate the probability.
