Question 751564
A recent survey found that 62% of adults misplace their car keys on a regular basis.. Assume a sample size of 42 adults.
 
E) Find the probability that at least 26 adults misplace thier keys on a regular basis

Binomial problem with n = 42 and p(misplace) = 0.62
----
P(26<= x <=42) = 1 - P(0<= z <=25) = 1 - binomcdf(42,0.62,25)= 0.5729
