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.
