Imagine that 200 mice are sent through the maze one at a time. The researchers believed that the probability of a

mouse turning left due to the food is 0.7. How many left turns would they expect from 200 mice?

Answer: We expect 140 mice to turn left.

Step-by-step explanation:

Given : The researchers believed that the probability of a mouse turning left due to the food is 0.7.

So, if we imagine that 200 mice are sent through the maze one at a time ...

Then, the number of mice we expect that turned left = (Probability of a mouse turning left) x (Total mice)

Therefore, the number of mice we expect that turned left = (0.7) x (200)

i. e. the number of mice we expect that turned left = 140

Hence, We expect 140 mice to turn left.
