Question

Three quarters of commuters drive alone. What's the probability p that among 200 commuter vehicles chosen at random 150 or more are occupied by just one person?

Answer 1

I'm not forsure on these questions...

Answer 2

3/4 = alone
1/4 = not alone
50/200 are not alone
50/200 = 1/4
same proportion, then maybe 100%?

Answer 3

out of 200
50 drive alone
150 drive with someone
50/200=.25
so 25% probability
