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

Answer: 262,000? I'm just guessing

Step-by-step explanation:

one product costs $14 to produce. It is mentioned that you need to produce 14,000 products or items, so you multiply 14 by 14,000 to know the total cost of producing 14,000 items or products, the answer is 196,000, remember there is also a start-up cost of 66,000. So you must add 196,000 to 66,000 which leads to 262,000. Hope this helps :)
