Unformatted text preview: X ~ Binomial (n=7, p=1/3) Assume now that, now he purchases one cheesecake each day for the next 365 days. Use the normal approximation to find the probability that he purchases at least 100 strawberry X~ Binomial (n=365, p=1/3) Condition: np=121.67>5 Nq=243.44>5 X approx.= G(u=np=121.67, =root npq=9.01 P (X>=100) P (X>99.5) Elena is lost in the forest. The length of time (in minutes) that Stefan takes to find Elena is normally distributed with mean 15 min and standard deviation 1.5 min. Find the probability that Stefan finds Elena in less than 14 min. X= length of time that s finds Elena, X ~ G(15, 1.5) Find P(X<14) standardize and calculate using Gaussian tables...
