Step-by-step explanation:
µ = 50
σ = 8
We are supposed to find the probability that the high temperature on October 31 in a randomly chosen year will be between 46 degrees and 58 degrees

Formula : 
at x = 46


Refer the z table for p value
p value = 0.3085
at x = 58


Refer the z table for p value
p value = 0.8413

Hence the probability that the high temperature on October 31 in a randomly chosen year will be between 46 degrees and 58 degrees is 0.5328
