Question 520348: 78% of lobsters caught along the Maine coast have a larger right claw than left claw. If a lobster boat pulls into the Fishermen's Pier with 400 lobsters, what is the probability that:
a.) 350 or more lobsters will have a larger right claw?
b.) 325 or fewer lobsters will have a larger right claw?

You can put this solution on YOUR website! 78% of lobsters caught along the Maine coast have a larger right claw than left claw. If a lobster boat pulls into the Fishermen's Pier with 400 lobsters, what is the probability that:
Binomial Problem with n = 400 and p(large right) = 0.78
-----
a.) 350 or more lobsters will have a larger right claw?
P(350 <= x <= 400) = 1 - binomcdf(400,0.78,349) = 0.0000007616
-------------------------------------------------------------------
b.) 325 or fewer lobsters will have a larger right claw?
P(0<= x<= 325) = binomcdf(400,0.78,325) = 0.9505
