Please Help! Probability Question

Question

1. Refer to #6. Suppose that after several trials, the experiment is modified to allow the monkey to look into the box while choosing a shape. The table shows the results.

b) Determine the experimental probability

of the complementary event.

c) What might this suggest to the science

researchers? Explain your reasoning.

Question #6 In a lab study of learned behaviours,

monkeys are taught to reach into a box

and randomly choose a shape from the

ones shown. If the monkey chooses any

shape that is not red, he gets a reward. If

he chooses a red shape, he gets nothing.

By monitoring the monkey’s behaviour as

several trials are carried out, scientists can

see whether there is any evidence that the

monkey is able to recognize red.

Answer 1

Hi,

Experimental probability is calculated based on the results of an experiment. Theoretical probability is calculated based on expected results.

Objective of the experiment: See if the monkey recognizes the color red by rewarding him every time he picks a shape that is NOT red.

Event: Not choosing red

Total number of trials: Choosing red + not choosing red = 2 + 58 = 60

P(not choosing red) = 58/60

= 58/60

Based on the results provided, looks like the monkey DOES recognize red.
