The table of the number of dolphins is used to illustrate probability

The probability that a dolphin group is partaking in travel is 0.2063

<h3>How to determine the probability</h3>

From the table, we have:

The total number of dolphin group = 189
The total number of dolphin group that partake in travel = 39

So, the probability that a dolphin group is partaking in travel is calculated as:

p = 39/189

Divide

p = 0.2063

Hence, the probability that a dolphin group is partaking in travel is 0.2063
