Amarine biologist has historical records to show that the chance of finding shrimp in a cath of ocean animals is 20 percent. the simulation below models the experimental probability of finding shrimp in at least one of the next 5 catches. the numbers 1 and 2 represent catches with shrimp. the numbers 3-10 represent catches without shrimp. what does the marine biologist do?

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
