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

Using the given functions, it is found that:

  • Lower total cost at Jump-n-Play: 40, 64.
  • Lower total cost at Bounce house: 28, 8, 30.
  • Same total cost at both locations: 32.

<h3>What are the cost functions?</h3>

For n visits to Jump-n-play, the cost is:

J(n) = 189 + 3n.

For n visits to Bounce Word, the cost is:

B(n) = 125 + 5n.

Comparing them, we have that:

J(n) < B(n)

189 + 3n < 125 + 5n

64 < 2n

n > 32

Hence:

  • For less than 32 visits, the cost at Bounce World is lower.
  • For more than 32 visits, the cost at Jump-n-play is lower.

Hence:

  • Lower total cost at Jump-n-Play: 40, 64.
  • Lower total cost at Bounce house: 28, 8, 30.
  • Same total cost at both locations: 32.
