Group Title
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?

since no stats are given as to ambidextrous peoples ... P(l) = .15, P(r) = .85 at least one is P(l) lr + ll

the 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?

ll+lr+rl+rr = 1 lr+rl+rr = 1  ll since l = .15 ... 1  .15^2 = .9775
