Statistical Literacy When considering a new carnival
game, the operators consider the random variable x
representing the number of wins a player gets out
of 20 attempts. One new game was found to have
an expected value of 7.4 wins out of 20, and the
probability of getting more than 10 wins was found to
be 7.8%. The probability of getting less than 2 wins
was 0.1%. The number of wins out of 20 had a
standard deviation of 2.2 wins.
Match the numerical values from the problem to the
corresponding symbols. If a symbol does not have a
corresponding value and cannot be easily computed
from the given information, then mark it as "N/A."
