In a population of 500 voters, 40% belong to Party X. A simple random sample of 60 voters is taken. What is the chance that a majority (more than 50%) of the sampled voters belong to Party X?

this is a binomial problem n = 500 , p = .4 , we want probability more than 50% of 500 chose party X. so more than 250 So we want the cumulative probability of x = 251 , 252, 253, ... 499 , 500 Do you have a solution in your book?
the speed of the canadian goose is 35 km / 45 minutes = (35/45) km / min the speed of the hummingbird is 35 km/ 60 minutes = (35/60) km / min ok so far? now lets change to km/hr
ok

wait I did this wrong
this is a binomial problem n = 60, p = .4 , we want probability more than 50% of a sample of 60 chose party X. So we want probability of more than 30 So we want the cumulative probability of x = 31 , 32, 33, ...58,59,60
So I got .044480
on a TI 83 calculator you can solve 1 - binomcdf( 60, .4, 30) , that will give you probability there is more than 50% choosing party x in your sample

In an egg carton there are 12 eggs, of which 9 are hard-boiled and 3 are raw. Six of the eggs are chosen at random to take to a picnic (yes, the draws are made without replacement). Find the chance that at least one of the chosen eggs is raw.
