Approximately 15% of peole are lefthanded. If two people are selected at random, what is the probability of the following events?
P(At least one is righthanded)?
Is this correct?
1P(none are RH)
so..1P(LH and LH)
1(.85)(.85)
=1.7225
=.2775...is this correct?

Best ResponseYou've already chosen the best response.1since no stats are given as to ambidextrous peoples ... P(l) = .15, P(r) = .85 at least one is P(l) lr + ll

Best ResponseYou've already chosen the best response.1the possible ways to choose 2 people are: ll .15*.15 lr .15*.85 rl .85*.15 rr .85*.85 at least 1 r in it is: lr + rl + rr does that sound right?

Best ResponseYou've already chosen the best response.0wait so is the answer .85?

Best ResponseYou've already chosen the best response.1ll+lr+rl+rr = 1 lr+rl+rr = 1  ll since l = .15 ... 1  .15^2 = .9775
