Answer:
0.099, 0.969,0.87,8.3.1.063
Step-by-step explanation:
Let X be the left handed people in the sample of 10 people selected.
X is binomial with n=10 and p = 0.13
a) the probability that there are exactly 3 lefties in the group
=
b) the probability that there are at least 3 lefties in the group
=
Now Y number of right handers is binomial with n =10 and p = 0.87
c) the expected number of right-handers in the group.

d) the standard deviation of the number of right-handers in the group
=
