Wolves in New Mexico and Arizona were historically 60% male and 40% female. However, after cattle ranchers exterminated many wolves starting in 1918, the population shifted to 70% male and 30% female. Biologists believe males are more likely than females to return to areas where the wolf population has been reduced.

1. Before 1918, approximately
60%
of the wolves in the New Mexico and Arizona region were
male, and
40%
were female. However, cattle ranchers in this area have made a
determined effort to exterminate wolves. From 1918 to the
present, approximately
70%
of wolves in the region are male, and
30%
are female. Biologists suspect that male wolves are more likely
than females to return to an area where the population has been
greatly reduced. (Round your answers to three decimal places.)
What is the probability that
8
or more were female?
