3. Mr. Voss and Mr. Cull bowl every Tuesday night. Over the past few years, Mr. Voss's scores have been approximately Normally distributed with a mean of 212 and a standard deviation of 31. During the same period, Mr. Cull's scores have also been approximately Normally distributed with a mean of 230 and a standard deviation of 40. a. Assuming their scores are independent, what is the probability that Mr. Voss scores higher than Mr. Cull on a randomly-selected Tuesday night? V:M=212 6= 31 C: M=230 6=40 M=212-230=-18 6? - ५० b. Assuming their scores are independent, what is the probability that Mr. Cull scores more than 50 points higher than Mr. Voss on a randomly-selected Tuesday night?

Transcribed Image Text:3. Mr. Voss and Mr. Cull bowl every Tuesday night. Over the past few years, Mr. Voss's scores have
been approximately Normally distributed with a mean of 212 and a standard deviation of 31.
During the same period, Mr. Cull's scores have also been approximately Normally distributed with
a mean of 230 and a standard deviation of 40.
a. Assuming their scores are independent, what is the probability that Mr. Voss scores higher
than Mr. Cull on a randomly-selected Tuesday night?
V: M=212 6= 31
M=212-230=18
