12 of the top 20 finishers in the 2009 pga tour used a titleist brand gold ball. suppose there results are repersentitive of the probility that a rendomly selected pga tour player uses a titlest golf ball. for a sample of 15 pga tour, make the following calculations.
A) Compute the probability that exaactly 10 of the 15 players use titlest
b) Compute the pobability that more than 10 of the 15 use titlest
c) For a sample size of 15 compute the expected number of players who used a titlest
D) Compute the variance and standard deviation
